markings that look like govt'.

I'll get pics up eventually, if there is anything to this but the here's what it's marked:

mid way down the barrel it's got winchester markings, and model 67-22 short long and long rifle. And a serial number with those punched numbers 014XX.

But the weird markings are by the chamber. It says "M.192 1947" Right over the chamber on top of the barrel. Then on the left side of the chamber on the barrel, right where it meets the wood there are 3 very small markings. Two of them are right by each other and they have a crown over a letter. I think one of the letters is an E and the other has a P, but the one with the P has an X over it, sideways. Under the crown. And the the third is an oval with a P and some other lines in it.

Is this strange? Or Govt' markings? I've never seen markings like this before.
