Thank you, Sir.

Thought it might be something like that, but the 15 or so that share my home all are marked 2.222. The only exception is A.G. Parker s/n 0019, a converted LM-!! with a Parker 23-inch barrel and a gold front sight, marked as 2.21.

Perhaps sombody was thinking about 7.62s when they stamped this one.
