M13 link - manufacturer codes


#1

I was assembling some 7.62x51 link and noticed that I had link with several different stampings. A quick Google search told me that MBO was Maribyrnong, Victoria, Australia and that GCK was George K. Garret Co. Industries Inc. Philadelphia, PA, USA. However, I couldn’t find anything for the following:
H1
H2
H3
H4
H5
H6
J

Anyone know who these manufacturers are?

Thanks Brian,

That is where I found the info on the MBO and GCK clips but was hoping someone here might be able to shed some light on the “unknown”.
