This is one of the Swiss conversions I have similar to yours and it looks like you have all the parts plus a swiss rifle adaptor cartridge.
To get a idea of value you can go to Simpson, LTD
www.simpsonltd.com and look at their last few pages under luger accessories.
I forgot to add. Take a look at the primer pocket and see it it has the three flash holes and center anvil, if so it takes the seperate berdan primers and balls like the unit I show.
