Some quick snaps of the National, had a quick play and all functioning.

Thanks for the update. Looking good and I'm pleased its functioning well for you.

I'm guessing that somewhere in its life, someone has replaced the motor with that from a Mark V, which would explain the off-white colour. Not sure why the heat tunnel is white though, never seen a National Machine with a square and white tunnel and the Mark V tunnel is tubular. Maybe someone just painted it white? (See photo of a Mark V, below.)

Looks to be in much the original condition that mine was in: The internal wiring is the same, fabric wound stuff and the heater and the way it's mounted is the same as well.

The difference - and I was expecting it - is the rheostat. Yours seems to have - what must be - a later modification, which changed the "flat-pack" style of fixed-resistances that mine had, with a more up-to-date (for the time) wire-wound and circular resistance. I think this is also why Lanzetter added the additional ON-OFF switch, as the circular rheostat did not have an OFF position, whereas the "flat-pack" version that my older one has, has the first stud-contact not connected to anything, thereby isolating the motor from the mains voltage when turned to off.

What's still the case, is that they were both just as unsafe really - even by standards back then - mainly due to the unprotected, mains-potential connections on the rheostat. It would have been a relatively simple thing to incorporate some form of protective cover over that area, to make it safer.

All the same, a good acquisition as it is and an even better one, once you have spent some time on it.
Good catch!

George.

Thanks Moose, interesting info re the motor etc. The ad did say the motor had been replaced at some point.

I noticed the rheostat was different to yours with the button type connectors but otherwise much the same everywhere else.

Oldhippy, that's what I'm hoping for, prior to this I've only ever cleaned by hand and had acceptable results but it's time consuming. There's something that niggles at me regarding ultrasonics so never used one but always fancied a proper watch cleaning machine mainly because I love gadget y things. 

Interestingly, I swapped a few messages with a fella on a group who started his career at Lanzetters, 2 brothers, one who dealt with the accrual watchmaking side and the other, the tools such as this and he worked on both departments, watchmaking after the tools section stopped.

    • I don't have one with me but the original should be 1.05 high for a 10.5 barrel.
    • As mentioned, brand new GR mainsprings do not usually require lubrication. You have observed my videos on YT where I apply a little grease to automatic watches to the barrel wall. As has been mentioned above, this is braking grease. The mainspring also has an extremely light (and I mean extremely light) application of 8200 along it's length also. I do not film every aspect of what I do as some tasks are a royal pain in the rear to film. This is one of those tasks. Although I do cover this in the video course. The videos on YT are usually a 30 minute give or take condensing of a job that may last hours I cannot film everything. If you look hard enough you may notice many places seemingly not lubricated - this doesnt mean those friction points were not dealt with. My YT videos are there for entertainment purposes and whilst many find them extremely useful as a learning aid, they are not comprehensive breakdowns of a full service, that would make them hours long each., my course on the other hand is a full breakdown of all steps required to effectively service a watch. I hope this clears things up  
    • Whats your thinking behind this? As a novice, looking at the dimensions, I would have gone for your original suggestion. 
    • In theory you can work ruby with anything harder or as hard (diamond is worked with diamond), but it's so easy and cheap to get diamond lapping compounds and powders that it's really the way to go. I'd suggest a copper lap rotated in the lathe, but almost any material is ok- acrylic, iron, etc. For pallet faces I would use 1micron diamond, it will cut slowly but surely and leave an entirely satisfactory finish.
    • I picked this little Russian up and was enamored by the dial. When it arrived I discovered it had the stout Vostok 2209 movement. I found it was a very clean movement and only needed to be adjust for timing just a bit. The dial that had my attention looked to be silver plated copper with a rather dirty looking patina. The dial isn't engraved as I had hoped, but was stamped with the pattern formed during that process. I wanted to make that pattern pop so I painted the entire dial flat black and used thinner to remove paint only from the top surfaces. Was a bit tricky to accomplish but I think it came out great. Next I turned my attention to the hands. Somene had put a shiny black varnish on the hands as contrast, no lume was present. So I cleaned that of and since I didn't have any white paint, I used liquid white out. I know this is probably blasphemous, but it's a totally temporary solution until I get some lume I like. Placing the hands back on was a bit tricky as the fit was incredibly tight and tough to accomplish with my  huge sausage fingers. I have a black leather strap on order for it. Very pleased with the results. Thank you for reading this.
