I have a question on the RAF decal-ed machines. ISMACS shows the decals were used on Singer 15's circa 1935 to 1950's.
I just bought a Singer 15 with the RAF decal set that the serial number dates to 1961. It's a 15k110 with top bed drop feed. Does this mean my machine is likely a re-do and not original? Because it's in great shape but sure looks original. Well, except for the chrome handwheel since that model should have a solid one.
