There is NO manufacture Date "on the Receiver Ring" for the Austro-Hungarian-accepted M95s....the acceptance date is stamped on the Barrel re-inforce, as "W-n..Eagle..two digit year"...a feature which is "overstamped" by as Large "S"
in the M95/30 conversions to 8x56R. ( Budapest accepted rifles ( for the purely Hungarian part of the A-H Army) have the Hungarian Shield Crest and "Bp" ( Budapest) and year digits.)
As to Acceptance date, it usually matches the Manufacturing date (year) but not always....given the over-run from one year to the next, and also the Possibility of a New Barrel being installed...given that in the AH ordnance system, the BARREL was "The Ordnance" ( and not the receiver)...Newly barrelled M95/30s (8x56R) sometimes have an acceptance of "34 or 37", being when a brand New Barrel was installed.
Czech-accepted M95 rifles ( 1920-24) were usually marked with a Czech Military District Marking, such as "S Lion 6 or S Lion 2", but usually have no "Acceptance Date" like Czech-accepted Mausers ( "E Lion 24").
Some good close-up, clear photos of your rifle would be a great help...Receiver, Barrel re-inforce, etc.
