help to identify this enfield 22 trainer

Can anyone help to identify the markings on this rifle? Be happy to add info or pics if requested.

No2mk4 22 trainer

Ftr 1954

BSA receiver undetirmined date as it has been linished off,

G.R Cipher ~ Georgius Rex (King George V) 1911-1936,

Looks to have the Weedon star on the under side of the wrist

L - Long Butt as they came in 4 lengths I think, Bantam, Short, Medium (Normal?), Long (could be wrong there)

I will see what the 76/GE & 38/GE turns up.

Could that partially linished original mfr date be 1917? Is the rifle built on a Mk3 or 3* receiver?

Thank you for the comments gentlemen - a few additional pictures.

Make sure the butt stock bolt doesn't have the square section on the end, or you will have to remove the forend before you attach or remove the butt stock.

Mark III receiver, it seems to me.

So it is giove. Maybe the top of a 3 or a 5 then, the last digit of what is left of the original date......
