The guy selling the original Luger attaching iron on eBay [rwcutah] is a good guy; I've bought stuff from him, but $195 is too high, IMO...
The two other 'stock iron' auctions are screw sets + punch, by a certain Ken K. DBA 'Revshop'...No iron itself; just the screws and punch, little stuff...
Sirplus70 frequently has repro stock irons on eBay; I'm waiting for Dorothy to post another Luger iron...
