Ring ID

[Baby]

I've worked my way up to the P & Cs. Planning to re-use the rings, assuming the end gaps measure up. I notice there aren't any markings on the first compression ring and the oil ring. The second compression ring has "TOP" stamped into the top. I'm curious about what I have here.

Here are a couple pics of the first compression ring. Is it stock or maybe some other ring?
