FEG B9R questions...

[TuscoTodd]

I recently acquired 2 FEG B9R's (.380) pistols. Unfortunately, they are both missing their magazines and one is missing it's firing pin and spring. Does anyone have a source for these items? Can P9R parts (9mm) or others be used?
Also, the one pistol has a very unique serial number. Instead of the standard 6 or so strictly numeric number, this pistol's serial number is "PT-xxx". Anyone know what the PT designates? This pistol looks desidedly older than the other and I would like to find out if it is something special or not.
I appeciate any help you guys/gals can provide!
Thanks in advance!
Todd :D
