Oiler Question

[USGI]

GI oilers I've seen from early 70's packaging are unmarked. I'll have to look at one of mine to see, but believe it has a rubber washer or o-ring. They might be flatter on the end than WWII issue, but not sure. If so, they should be easy to stamp whatever you want on them. Saw one on eBay a few years back that was stamped Inland, etc. on the side. Members here figured it was a reproduction of some kind. - Bob
