I agree with Alan & Thunderbox, the early Enforcers should all be engraved within a single ovoid! If these were all engraved to the same pattern possibly with some form of jig, then this one is totally wrong! (The E of Enforcer and D of the EFD logo should be inline).

Enfield would not have changed the pattern for one rifle!

A late Enfield replacement for a damaged receiver possibly? Probably not as there were spares existing at Enfield that would have been just swapped for the next available serial number!

Looking at pictures I have of about 70 Enforcers, and the style of lettering layout and format, this rifle should be numbered at least 403.

But as we always say with Enfield strange things happen
