I just got this gun and thought Id see if anybody knows anything about it. Serial number 13 and 0 is all the id on the gun. It has a lot of non typical features that I dont recognize from anything else. Rectangle cross bolt, spring loaded individual extractors(I am wondering if they were unfinished ejectors) When the toplever is pushed to open the gun, it partially cocks the fired hammers, then they are fully cocked by the barrels dropping open and pushing the cocking rod back(round rod seen under the watertable)
