Wartime FN Browning 1922 trigger guard and slide marks meaning

[crowtalks]

I have a FN Browning 1922 and on the left side of the trigger guard it has MR and on the left slide it has (H)

Does anyone have any information on what that means, and the possibly the years it was used?

This should be asked in the thread you already have open about that gun.

Closed.
