Thanks Darryl,
It was advertised as a 45, but when I got it home and looked at the tag it says Model 33. Either way, now that I've restored the blades' sharp edges it produces a super cut. I wish there was some way of finding out how old it is, the serial number doesn't really give much away, so far all I can gather is between 1960 and somewhere in the 1970s, when did they stop production of the 33?
Cheers,
Kelsey
