Headstamp question

[ARGarrison]

I just got some old British .303 ammo and my only source list only US headstamps. Does anyone know of a sorce for International headstamp code?

What I have and am looking for is GB, RG, B /1\ E, R /1\ L. The 1 should only be a straight line, but beats me who to make it. It should look like a arrow pointed up. I also have some that look like CB, but could just be a poor stamp of GB.

Either way thanks for the help.

GB= Greenwood & Batley
