So I recently purchased numerous lots of ammo off the internet (1 from the EE). I just got done going through the various En bloc clips and stamps. I don't know if any of these are rare/valuable/collectible or not. Let me know if something jumps out at you.
Here is what I have:
2 - blank
1 - MAS
16 - I S (1-5) (some with upside down numbers)
1 - W 7
2 - W 5
1 - S
2 - LP 1961
1 - LP 1956
1 - L&H 81
1 - WEP 1
1 - WEP 5
2 - WEP
4 - NW
4 - AEC
6 - SA line above and below
6 - JMO
11 - BLM
6 - WRA
More than I wanna count 20+ - BRW (1-7)
More than I wanna count 20+ - DAQ

WRA. Winchester, dont loose those

Do they have small holes stamped out on each side near the round detent areas? Pictures.

Everytime I find I have a WRA clip I sell it for $40-50 because for me a clip is just a clip.  Earl
