This one is new to me... I don't know the serial yet But any guesses/bets welcomed! Battle scars from some nato action.. All I did was polywatch it, so far... Cleaned the "old skool" way.... movement pics to follow..
Can usually tell whether its the '67 or the '68 just by pusher feel, the 321 has a sort of shorter travel, crisper/finer click especially on resetting while the 861/1861 requires more force and feels more sturdy and solid.
Have confirmed its a 321 by slower beat tick tack sound compared to my 861 which beats at a faster rate.. The pusher test: it's short and crisp clicks on this, when compared to my 861 which is firm and sturdy.
