I'm far from an expert on these, but I'd like to venture to say it's a ground dug M42, which if I'm correct it shouldn't have a tri-color decal on it. Wait for others opinions though.

Should not have the tri color! Makes me question the other decal. Shell looks ok to me.

Nope, forget about this one. Just a ruined shell
Looks like it has been in a damp garage for the last
50 years. Mr. Avenger is correct - it should not
have a National decal on it, so a 'messed-with'
Hi, not one worth pursuing, a messed up relic M42 shell. Leon.
