Questions About My 1943 LB No. 4 Mk 1*

[WW2Buff]

I've got her totally torn down, Jim, and I sure can't see anything that remotely resembles any part of any of the marks in Stratton's Table 1-12. There isn't an ENGLAND stamp either, just the BNP stamps in the photo below.

Another question - anyone know the origin of the buttplate trap, marked PC?

Peter sorted the leaf sight. What about the SMC magazine?
