Unusual fxo with Excellent Bakelite Bottom

Good overall Haenel fxo code P.08 magazine. Excellent base, fair tube, very good blue. The tube has some dents. The base is uncracked and exceptional, as are the rivets, magazine appears in good function with very good follower. The magazine is not army accepted with E/37 stamps. I am inclined to think it has Luftwaffe use with the lack of E/37, or very late war.
