I need a cylinder pin catch spring for an Iver Johnson 1900 Double Action (.22).
It is a very small flat V-spring.
So far, I have been unable to locate a replacement or a suitable substitute.
Three attempts at modifying springs on hand just resulted in broken springs.
I was willing to give a coil spring a shot, but can't find anything small enough.
All 'general purpose'/'gunsmith assortment' type spring kits that I've looked at don't have good options for this spring.
So...
Do any of you have something suitable in your parts boxes?
Particulars:
No idea on spring weight required. Probably just a few ounces.
Compressed thickness less than 0.040".
Width: 0.085" max, 0.065" originally.
Length: 0.250" max, ~0.215" originally.
Since photos seem to always help (as simple as a V-spring is), here's a rendering of the spring, and a photo of the catch that retains the spring in the notch on the left side...
(Not necessarily to scale - I eyeballed the dimensions for the rendering.)
Just as a point of reference for scale, I could fit two of those catches on my thumbnail. It's a very small spring.
