    Hi guys,

    I have an 89C I'm trying to restore and I need the count lever, warning lever, and both strike hammer assemblies. The only parts movements I can seem to find are 89AL. Are the parts I need compatible, or do different 89 movements have different internals?

    That's a really big question. Many of the variances are to do with the different provisions for striking. A thread, maybe 6 months back, was about many internal differences in the strike train that were made over time, things that I had never noticed.

    Probably best to keep looking for a complete "C" movement. Even a photo won't help with some of the differences.

    But, as always, photos help.

    Yep, that's what I'm thinking. (Find another C) You never know what's changed on every one of them until you get into it.

    Thanks guys. I also had a hunch I should just find another C, just wanted to verify!

    Some of the 89's had a passing bell half-hour while others did the half-hour on the count wheel. I guess that means the count wheel would have 12 more teeth, On the time train, I believe the 3rd and 4th wheels on some versions were different. And the quarter strikers were different. I would guess that the strike levers would be th same on similar movements with the same type of half- hour strik.

    Hey there.

    There are two st 89Cs available on eBay as of right now. One listing is an auction and one is Buy It Now.

    I have one 'donor" in my Bone Yard which may be a "C". I'm not sure but will check later this evening.

    It's pretty rusty. I took some parts from it for another member here so it's already incomplete. If I have what you need, you can have it for postage but you'll have to clean up the rust yourself. I'm not doing that again if I can avoid it.

    I'll let you know one way or the other via a private conversation.

    Regards,

    Bruce

    Thanks guys. I’ll look up the C on eBay in case you don’t have what I need, Bruce.

    RC, mine has the half hour strike on a small bell.

    Chris, is this the movement I sent you the main wheel for?
