I have a early 1 million serial numbered Koshikowa ( sorry Grammer) with what looks like somone went a little crazy with a concentric circle stamp on the mum 2 strikes. it also is a school rifle with double school stamps. It also bares the two 00 serial 3 prefix.

Would you say this is a defaced mum or a removed from service stamp over the mum? I may be think the stamp guy was having a bad day when this was stamping it as out of service.

I present it to you the profesionals.

If you can post a picture, we can have an opinion.

Some mums were canceled with three large "O"s.

There are usually three circles, in the mum. Sometimes, the mum is surrounded by zeros. The rifle was removed from service, and relegated to school use.

there is a more faint 3rd circle on the mum. I will try to get pictures up in the AM.

Looks like someone had too much to drink! The character below the mum is "bun" (like boon) and signifies that it was taken out of military service and handed over to a school. The surprisingly deep circles is likewise a cancellation to remove it from service. Done nicely it looked like the stacked cannon ball symbol of the arsenal.
