There us not much light for a good photo but I quickly placed the movement back temporarily in its case for a portrait.

Made in my home town of Hull, 45 WhiteFriarGate. Which back then would have been the main shopping area, it had a shipping lane right at the top of the street. My son works just around the corner .I'll get you a photo of the shop next time I'm in town.

Thanks, with this you answered my next question as when to turn the pivot, I assume it also helps to do the length/adjust the end shake with this as you cannot be 100% certain how deep exactly you can push the new bit down.

Yes just turn down the part to the required diameter heat the pinion but not cherry red press fit part quench before heat transfers to new bit then turn pivot and shoulder to correct length for end shake.

I would recommend doing a test piece before doing the arbor, drill a hole in a bit of round bar of approximately same diameter as the pinion turn a bit of steel to required size heat and press fit then quench, that will tell you if the hole size is correct & roughly how long to heat & most importantly give you confidence to do the proper part especially if you do it more than once.

WhiteFriarGate where the clock was sold from . In the 70s, 60s, 30s, and late 1800s when the shop was still there.

The holder the blued steel is in looks like a gun shell, and it looks old so probably good quality blue steel, some of the new stuff is rubbish.

This video maybe of help to you to give you an idea of what’s involved.

needless to say it’s not how I would do it or suggest you do it but it’s just to give you an idea of what’s involved.

Dell it is a cardboard tube. My blue steel was in something very much like it and yes the steel is as hard as hell.

      How do you thread a screw on the lane without shearing it off?

      By caseback · Posted

      My second suspect would be the O1 tool steel. Is it still "soft" enough after the turning operation? If the part got hot, it might be work hardened, making it more difficult to thread and easier to break.

      @Mark Thanks for letting me know. I'll start a new thread. @AndyGSi Thanks too for that tip. I might be able to turn them down if need be. 🤞

      Bracelet Extender Sizing

      By Curare · Posted

      Thanks for that Andy, Yes the new bracelet is worth more than the watch itself, Its one I have bought to service and clean-up and on-sell it as a project, look it may sell to someone who has a small wrist, I think I will buy an extender and may-be offer it up with a normal strap as well CJ

      Unknown watch movement logo. Very interesting

      Not always that simple. Typically the only reason we would have any way of identifying a watch is if parts were available at any time and somebody had a parts reference book then they would help you to identify the watches that they have parts or. Unfortunately there are hundreds of thousands of watch movements with no identification and of course typically no parts the classic place were watches would be identified would be under the balance wheel and your pictures don't really show a good view of that. Occasionally I've seen watches marked under one of the plates. They felt very proud of their watch is a very prominent Swiss company and they ask he stamped the bottom of a plate so you have disassembled find it. Then there is the other system the keyless parts make up something called the fingerprint system but you still haven't given us enough information to make use of that. Here's an image showing what a fingerprint system looks like. The PDF is based on the physical book the physical book has sizes of watches these are smaller ladies watches and keyless parts which in the physical book are printed at the actual size of the watch parts. So to identify with the keyless we need in your case diameter measured on the dial side and a good picture of the keyless parts and then you have to hope that this was made within the right time span of the books that have this system on the other hand a lot of times on the dial side they will also put markings. So basically to identify a movement it has to come out of the case and has to be disassembled.
