Browsed trough the Biggerhammer magazine FAQ and was wondering the following

Both mags have dull alumuminium followers and are in about 90 % finish.

One has M16/M16A1 5.56 mm on it followed by Universal inds div. Below that Simmonds prec. prod. inc. West haven Conn. USA

The other has the Colt pony Colt AR15, below 5.56 mm w. Colt's data below.

Both have a C stam on the front side of the magazines.

Obviously these are both preban(which is of no concern to me over here), but I was wondering about the mfg year of both. I quess, looking at biggerhammers data, these are made somewhere between 68 and 79.
