Thanks for the info Muffet I will have another look at the 45 tomorrow at is is pretty easy to get to safe wise.
The 45 had on the left side of the barrel where the 6-59 was and that was an L atop number 24 and the broad arrow underneath that (Armourer ?)
Just a question what was the anomaly with the '21 if you could help there as I am interested in why the fore woods are still in the white how would that happen not being finished.
You can see the difference in the pics.

Thanks for the info on the 1916.

Funny thing is on the 45's butt it has MAO atop SMLE funny that !

I have a teak full wood on the 45 at present and the original stock is being preserved infact it is due for its BLOicon.
