I assumed the top lever on pomofo's gun must be for opening the breech since he has obviously opened it and the lock-up is apparently tight if he holds it to the left. If that is indeed the case, it probably wouldn't hurt anything to fire it, but I'd advise replacing the weak or broken top-lever spring ASAP because if it isn't held closed, the locking surfaces will get hammered. I only own one drilling, a C.K. Ansorg pre-war 16x16x8m/m. The barrel selector that also raises the rear sight is on the top tang, and the safety is on the grip.
