Hello Team,

does anyone have any information on Waltham 16S 1888 Grade 20? I am looking for specifications on the roller and keyless. 

I got a new balance staff, but am missing a roller table. Any suggestions where to pick one up?

Another problem is the yoke. It seems to be so impractically thin that I have a suspicion that mine was just broken in half.

I bought #18 here https://www.ebay.ca/itm/125216800551, but then realized that it is not what it should look like. The thin tip that slides into the grove is missing.

Any suggestions on sourcing parts and specs is highly appreciated.

Your best bet is to try to find another of the same size/model/grade on eBay HOWEVER be aware that even if you do parts may not be 100% interchangeable.

Here are 2 pages from the E&J SWIGART "Illustrated Manual of American Watch Movements"

Thanks Dmitry! I suspect that is more complete for the pre-1909 Waltham watches than the E&J SWIGART "Illustrated Manual of American Watch Movements". It's possible that at some point I'll have a Waltham open on the bench.

      Thanks Mark, but can we still discuss the other important matter please and not be distracted from it. Thank you.

      You're probably not going to see a dramatic change but you should probably figure out what the lift angle is as it probably is not 52°

      In tandem with my last post regarding the removal of Google Adsense on this website - I have also decided to fully self fund this site as a gift to the watch repair community of which I’ve been a member of, and have benefited from since being extremely lucky to gain an apprenticeship back in the late 80s.    Well, that means that I have also closed down my Patreon account - or, to be clear, stopped all future transactions on my Patreon account and this is with immediate and permanent effect.    not to mention, but I will, I really really do appreciate the contribution all my patreon and PayPal supporters have provided over the years, you guys have been absolutely awesome and helped to keep this forum alive and available for those who might not be able to afford the payments.    again, from the bottom of my heart thank you.

      My pleasure. I would rather pay more than have those annoying ads ruin this site. They were a terrible idea and something I never even saw much, but I was on my iPad yesterday testing a security update for the forum software and it was impossible. I decided then - they had to go!!! Also, co-incided with this, for those who are paying for pattern in order to help fund this site - I’ve just disabled patreon. Future monthly payments will not be taken.  PayPal is a little more complicated. I will try to work out how to cancel the few subscriptions but if you are a PayPal donator then please feel free to cancel the monthly sub.  I will, however thank you all from the bottom of my heart for helping to contribute to this site financially - it means a lot. But going forward, I’m funding it personally from my pocket and that’s the end of it 😄

      Thank you Mark it definitely makes the site looked much nicer. Although I didn't mind the ads as long as it helped to pay for the messageboard but sometimes when you had the feeling that there were more ads than message board yes it was a little annoying. Thank you
