Nice one - here is the brother buckle.
interest your variation with inject moldet prongs .......
Lovely ones! I've a hate/love relationship for the M4/24 and the zinc buckles but that relationship is about to turn to only love
(I don't have neither a M4/24 or a zinc but I will try to get one next I buy a buckle!)
I now read that this M4/24 Zinc is heavily faked so I really have to ask you guys before..
Shown here are only the original buckle. If you are in doubt before buying, put a photo here and we will be happy to help.
