While messing with it I over-stressed the mainspring and the end broke off.
So I ordered a new mainspring and cylinder hand. The mainspring arrived yesterday and I installed it and it works fine. I fired the gun just to see how the spring was working. Without a cylinder hand I simply cocked the hammer, carefully rolled the cylinder around until it was against the cylinder stop and then pulled the trigger. It worked fine.
A friend had sent me a cylinder hand that had a broken spring (I think it must be common with these guns) and I decided to see if I could re-spring it. Using an old Colt SAA hand spring that was broken, I finally got it put together. Now all I need to do is shorten it to the correct length.
Since I have a new hand coming, this will give me a backup. Always a good thing to have with old beat up cheap guns.

I have a set of original grips coming. Hopefully they will be here soon.
Self-Repaired Cylinder Hand .. note it's a little bitty thing. Note the new hammer spring
