Surpmil, could it possibly say FED ARMY Workshop? I ask because while I was in Malaya, we side-loaded both ways weaponry between the big Federation of Malaya Army workshops in a place called Batu Cantonment in /near Kuala Lumpur. We used to deal with them a lot. They had most of our old specialised equipment for things like Daimler Ferrets and mine proof Bedford QL and RL trucks while we had the specialised small arms kit.

If it could, then yours might be an ex Malay Army rifle. Just a thought.

There was a big range complex near there and they've recently de-jungled the area for logging and found a crashed Dakota plus the crew, lost since the 50's
