Win 21 parts

There are numbers stamped on the inside face of the ejectors.
Almost impossible to read but I'm fairly certain they are not the serial number.
Any ideas?

Why not take out the retaining screw, remove the ejectors and look directly at the numbers or glyphs?

Might be able to decipher them with a dental mirror, possibly.

I need a 21 ejector forend metal and/or wood. Thanks.

I was not so curious as to what actual numbers appear but why they weren't serialized to a gun. Thus far I've heard two plausible explanations.
1) Left and right extractors were produced as a set, and numbered so, then thrown in a bin well before they were fitted to a barrel yet now (then) existed as a set.
2) Left and right extractors were fitted to a barrel and assigned the same production number as say the barrel before the barrel was fitted and then serialized to a specific receiver.
