ISO 4SN parts

Submitted by Badmoon66 on July 15, 2021 - 4:49pm

Hello. I am in search of 2 parts for a Bulova 4SN movement. 

1 - 4SN barrel bridge

1 - 4SN click screw

If you have these or no where I might be able to source them, please let me know.

To be honest you have may more luck getting a complete (or near complete) 4SN movement off eBay than actually finding aparts.

Here's a reference incase someone can help.

Yes I agree and have been been checking ebay regularly. The 4sn has proven elusive thus far. So, I'm checking everywhere I can think of just in the off chance I get lucky.

Thank you for the reference pic.

I'll look through my 4 parts this afternoon but so far I'm mostly seeing 4A's. Will report back if I have your parts.

Hi again, I looked through all my 4's and I only have parts for 4AB, 4AE, 4AF, 4AH, 4AL, 4AR, 4AU, AND 4AZ. My interchangeable parts catalog doesn't include the 4SN movement and the Jules Borel catalog wasn't much help either. If you can determine whether the parts you need are interchangeable with any of these or other movements, let me know and I'll look for them. I have lots of 5 and 6 parts movements as well.

Thanks a lot for your time. I don't know the interchangeability off hand either but I'm gonna see if I can find out.

Thanks again,
