For the fun of it, I looked at the markings on my STEN magazines which are as follows:
The five that fit my mag well:
1. M634 with Broad Arrow (came with gun)
The four that were too tight:
6. E&CO (this one actually seemed like it would go in, and I noticed the #3 one above was slightly scuffed up where it goes in the mag well so I think this one will work with minor scuffing)
I'd like to get some more Broad Arrow marked ones if anyone has any in good condition.
Anyone know the manufacturers from the above codes? I got my Dial Caliper out, and there was like a .07 larger difference in the dimensions where the magazine goes in the mag well for the N93 stamped magazines.
All the magazines I have are in very good to excellent condition.
Any thoughts about these codes and findings?
P.S., I started to slowly work #6 thru #9 in and out of the mag well, and they started to move a little more freely. I also used a clean oily cloth to oil all the magazines before putting them away, and noticed the cloth was not completely clean so even though they look clean they may need some more cleaning to remove any residue that might be a factor.
