M17 mag box

[Doco overboard]

For some reason I believed the only riveted mag boxes were done by Eddystone. I was stripping a rifle and found this magazine box stamped with a W and thought it interesting.

Could anyone more knowledgeable say for sure~just wondering for my own behalf.
Thanks for any information someone could provide.

I've seen the same manufacturing process for both P14 and M1917 magazine boxes from all 3 maker's.

+1 I have seen all Three makers use rivets.....
