Raimey,
Thanks for your quick response, I'm almost sure about the "E" I was not so sure about the "K"; positive about the "A". They are silver inlaid in a rectangular device. Unfortunately I'm further north for a while, away from the drilling, and not too good with posting pictures anyway. There are NO makers marks on the barrel flats, bottoms of barrels, lumps or action face, I looked at ribs and loop and did not note any marks there that looked like a makers mark or logo either. Proofs are typical post 1894 with "nitro" on shotgun barrels and STMG etc. on rifle. Caliber stamped as "9" and "75". I couldn't find any match for action logo in my references; I plan to look tomorrow in references "at work".
Best, and thanks again,
Mal
