1900 broken toggle lock ?

I think this turned out to be the case.

BTW, there's a thread from not too long ago where a couple members were measuring the force needed to open the action fully. It was in the realm of attempting to discover if a spring was weak, and I don't remember if a 1900 was tested. There would definitely be some mechanical difference with the bell cranks of different arm length, the two styles/strength of spring, and the different masses of the toggle trains, 1900 v. 1906. However, I'm wondering if all the variables would simply work out the same when comparing a 1900 to a 1906, each of .30 Luger, i.e. the total opening force, and then force available to return to battery. A strong spring acting a short arm may be the same as a weaker spring acting on a longer arm-- same torque. One may need to account for speed in this equation, in accord with the different distances from the fulcrum.
