30-06 headstamp help with ID please

I had this down as Austrian but now not sure it is. I can not find a match on the headstamp. Any help welcome… Paul

Your cartridge was made at the Lake City (Missouri, USA) Army Ammunition Plant in 1954. It is a high pressure test cartridge with a tin plated brass case. Production started at Lake City in 1954 and continued through early 1955. Loading details are covered in HWS Vol. III, page 143.
