Hi Ron-E, welcome to the forum! Your mag was made for the new, 1970's re-introduction Mauser post war Parabellums... There are a few different variances in the magazine production to equip these new issue Lugers, but most proved unsatisfactory for any application other then the Mausers they were designed for.. they have a super bear strong spring.. and eventually the plastic bottom will blow out at the range... The value seems to run between $75.00 and $100.00 for one in nice shape... and broken ... anything they will bring... I've up-graded several and am currently up-grading eight for one forum member..

... my kinda guy!

... If you want to sell...I've always got $75.00 buck ready to go... best to you, til...lat'r...GT...
