I am trying to source a part for a Bersa Lusber 844 7.65mm. This, along with the 84, 622, and 644 were early Bersa models made in Argentina and intended for the Italian market in the late 1970s and early 1980s. If any of you know of parts sources for this pistol I'd appreciate hearing from you. The part I need is called the 'sear bar', also called 'cocking piece'. It's #44 on this schematic.

I've already tried all the usual places like Numrich, Popperts, Jack First, Eagle Imports, eBay, GunBroker, etc. so I'm casting a wider net.

Any assistance is appreciated.
