Newbie question, I just picked up 4, 20 round mags . They are all marked diferent . I was wondering if some were more rare then the others. One is marked "THE CROSBY CO." , the other is marked, "PATENTED-AUG.20,1920 AUG.24,1920-JAN.11,1921"
The other two are marked " AUTO ORDNANCE CORP BRIDGEPORT CONNECTICUT" Thanks for any info you might be able to share.
