BFG 866 Jewel Spring
HI All,
I know that the BFG 866 can have from 1 to 17 jewels.
So this is a question about the 17 (?) jewel movement.
There is a spring that give the movement some degree of shock protection, and I am trying to get the part number, and a description of it.
I think it is KIF 1-4.
That is the question?
The other thing is the top and bottom spring the same.
This is a spring with three "prongs" which sits atop the cap jewel.
Thanks as always for any and all responses.
Mel
