Thanks for the replies, the "lead screw' has no noticeable effect that I can detect. Whether it's in or out seems to make no difference.
It does look like the usual lock down bolt and lever were bypassed and 2 threaded holes added to the base for mounting?
This is an interesting find...
The knob unscrews as does the brass spacer & the threaded rod unscrews but that seems to be it.
The business end doesn't seem to come out when all is undone
It looks like it is hinged or something but I can't get it to move other than rotate with the spindle.
It was made in 1944 & the movement is a 26.5T3
The bezel can be either steel or gold colored - I've found similar watches with either.
There is no reference number on my case but this eBay item is similar 114075987288
Hi John & Jim,
I have just double checked - it is definitely the original pendulum and measuring just now it seems to be the correct 15" to the regulating nut.
My bob is the 2 7/16" but coming in at 124.3 grams on my scale.
I have a Pequegnat Brandon regulator I am trying to regulate. I'm quite sure it is all original but it's running fast - I've lowered the bob about as far as I can but it is still gaining time
I am not a clockmaker, I'm just trying to work out how else to slow it down...
