I'm looking for info on my No4 Mk1.

It has a 1/49 date of manufacture and the ser. num. it PF73XXX,

From my research (I may be wrong on this) it was made at ROF Fazakerley Lankashire ( code "F" )

It has crossed flags Inspection mark ( looks like S Africa.but has no letter designation in the mark)

It has a "U" with a downward pointing arrow in it.

Thank you for any help you can give.

the pic is of the "U" on top of the reciever,I can provide pics of other marks if needed.

This is a very interesting rifle (to me) and would like to know more about it.
