Borel's part number for the staff is 100/373. They also carry mainsprings too for the 157.
MAINSPRING 1.40-.12-320 9,5 and is part number MS-5595M
Gruen listed the spring as being 1.45x.12x330 which is pretty darn close.

All I know is based on hard work & writing by others. I can only aspire to augment this body of knowledge. If I am wrong it is because of my own failings. -me
