Paul St. PierreCorrect spec for a Hamilton 2974B Balance Staff
I nearly cried when my 1942 Hamilton 2974B hit the hardwood floor from a three-foot drop, in the vertical crown-up position, impacting at the 6-oclock position. No damage to casing, crystal or dial, but as you would guess, a broken balance staff.
Would a kind savvy please list the spec of this balance staff to enable ordering the correct one (e.g. pivot size 0.09, .10 or .11? etc) and maybe where I could find it.

Paul D. TrombleyPaul, I've had good luck listing my parts request in the
Horological Items Wanted section...
Sometimes you get a gracious offer from someone who has one laying around and glad to see it go to a new home... or members with stores willing to sell you a part at the "family and friends" rate...
One of the many perks of our membership and fellowship here.

David AbbePaul, I remember that it was a 992B type staff, though I do not remember if that is a friction fit or riveted type staff. You may have to remove it to determine.
The part numbers are in our tech section cc of all the Hamilton part numbers at;

Richard M. JonesPaul I have several vials of Hamilton Staffs, all Bestfit. If you can figure out what you need I will send you one. What I have is as follows with Bestfit numbers, all 16 size: 435SR 434DR 992DR 950-950B 992FR.I acquired a 72 vial Bestfit assortment and they are all in excellent shape and seem to be correct.

Paul St. PierreI do thank you, kind gentlemen, for your responses. Richard, in particular, many thanks for your offer. All I need to do is to find out the correct spec of this staff, which is the reason I first started this thread.

Paul St. PierreAnd I'm sure this basic question has been asked before: Does the Hamilton 2974B have the same movement as the 974? If this is true, maybe the 435SR is what we are after.

Gary E. CochranPaul,
I am not sure about the staff but the movement looks more like a 992b movement than a 974 movement..I would suggest you contact Larry Crutsinger at detent21@aol.com I am sure he could help you...Gary
