What am I doing wrong.  I cannot find Elgin numbers this low in the Bestfit nor Marshall handbooks.

@JohnR725I know you have the answer.

you do know that you being extremely lucky in that if someone makes a reference to me the chance to me ever seeing it is practically nonexistent. I don't quite seem to spend as much time here as I used do so I miss a lot of things but since I was just here answering something

typically I never think of Elgin watches at least pocket watches in either of those books although I do note the back of the bestfit book does have a Hamilton Elgin section nice for cross-referencing Hamilton numbers I typically never think of them for pocket watches

so usually something like this I would take the serial number of which you conveniently gave us go to the pocket watch database on the left-hand side it says parts click on that you get a parts list what were you looking for?

Then of course the other thing I do is I usually look in because I have is a PDF the 1915 Elgin parts Log as it's a picture catalog it's much nicer than the later one.

then it was things like a balance staff that I'll go look at another book after you get the number to see just how many variations exist because that isn't always visible in the parts book of how many variations it might tell you their variations exist they just don't tell you how many variations.

Elgin grade 428 part numbers for the balance as follows:

p/n 2552 - balance

p/n 4175 - balance complete

p/n 2653 - roller without pin

p/n 2699 - roller w/pin

p/n 4136 - balance staff

In 1949 Elgin charged $0.50 for a single balance staff.

not as bad as usual for Elgin at least you only have two pivots sizes and don't have a bunch of other variations for size for the same part number like the older ones

There was a note suggesting there was more information in the "special section" which I'll be dipped if I can find. I suspect that the pivot variation that John shows would be what we'd find if I could find the "Special Information Section".

These guys will sell you one for $15...

yes the problem with finding the fine print in that Will look then of course there's also this website

http://www.elginwatchparts.com/

you'll notice that when you enter in your model number it does have the notes on the bottom but it refers you to sections for some of it which then you don't half but it does give you a clue is going to be variations

Where did this come from?  Do these numbers correspond to all of the other dimensions of the staff?  Is there a diagram to correlate with?  Like this?image.png.24ecbf46e79e64ca07ecf669edb50e25.png

I had acquired the book by going to a regional is also a companion one for jewels. Somebody finally made it into a PDF I've seen the staff one on eBay. Then yes the numbers correspond to the other numbers. There is no picture at the very top of each page they just list whatever the dimensions are usually works best when I'm stepping things out if I get the top of the page that your staff was at the bottom of the page.

then I snipped out an image of the other books you can see what it is it's interesting because it went through and measured a huge assortment and that lets you look up staffs by size. With at the bonus at the end of the book they have all the various technical literature of various American watch companies. Plus if you're lucky a few of the staffs have all the dimensions more than you normally see in the list were somebody went to into the detail like you're going to make a balance staff but not all the staffs are listed in the back just some of them

but typically the first book one I got your numbers from whenever I need a staff that's where I go unlock because then you can see all the verifications because most people don't realize that one number could refer while is one Elgin actually refers to 12 different staffs I think there's three or four groupings of differences for variations and all the rest the differences are the pivots size there's very few staffs that you only have one staff with no variation but they do exist there just in the minority

then of course what makes this one interesting of the Swartchild's American Balance I think almost no one knows it hacks even exist it have to have literature from the material house and I was at a regional meeting just picked up some stuff is as always on the hunt for literature. I'm guessing somebody on eBay just scanned it and probably is not worrying about the fact that assesses copyrighted on the bottom of the page but it does become an interesting book to have

    • I did that also for a few movements - well, mainly in/around the train jewels. I made big efforts to epilame the mainplate WITHOUT getting Epilame into the Pallet fork jewels (where it's not supposed to be, right?). I made litte barriers with Rodico around that jewel and used drops from a syringe to apply on the rest.  However, I've now stopped doing this. For three reasons: 1. It's a hassle and consumes more of this liquid gold. 2. I didn't see the need when using HP1000/HP1300 lubricants and grease for most part. The two places where I'd use 9010 (i.e. escape wheel and balance) receive Epilame in specific places... or the cap-jewel-setting of the balance suspends the oil sufficiently be capillary action (see my "conflict" about using Epilame on the balance jewels).  3. Lastly, and here I really wonder about yours and others' experiences: I felt that applying Epliame to the train jewels left them looking hazy (borderline dirty) compared to the (painstakingly achieved) sparkly clean results of my cleaning process. I just can't help but think that the Epilame residuals would mix with the oil and cause more friction/wear. I don't know.    simple: it'll stay there. It won't move any further. That's exactly what is happening if you epilame a cap stone. You end up placing the 9010 right on top of the epilame and the oil will sit nicely on that spot.
    • There are some parts on Ebay for the seiko 6020A, it may just be a waiting game for someone to strip one down, NOS will be more scarce . K would strip your movement down to the module then start looking at other seiko movement to see if that coil is used, then seek out a seiko part dealer. Also Retrowatches youtube owner Mike may give you some advice try him on his site . He also hangs around amateur watchmaking groups.
    • I would agree, in order to work harden something you need to exceed it's yield strength when it moves from the elastic zone to the plastic zone and you get permanent deformation and work hardening which is fairly close to its failure point, relatively speaking and dependent on the material/alloy of course. In theory you can load something constantly within its elastic range and not suffer work hardening issues.
    • Probably easier to get a complete new movement - but CousinsUK list it as discontinued. Maybe someone on here knows a substitute movement ?
    • Any other thoughts on how I can get a replacement coil? Any “hidden” or unknown physical shops (in Australia or elsewhere) that might have them in stock (but not always online)?
