394.1
389.8

Low 387.4

High 408.7

Ave 394.5

Extreme Spread 21.35:confusion:

Looks like a major service could be on the horizon for the old girl including a new Mainspring. I feel that she is worth a bit of TLC as she is in pretty good cosmetic shape.

Could any of you guys recommend a new mainspring for me. Also while I have the gun stripped down, any other parts you would recommend replacing?

Cheers
