"Very nice" is an understatement ... this is perhaps the rarest of the old pre-500-series Kirbys -- the Model R (retail) with the switch in the handle. And it's complete and in the boxes. "The stuff dreams are made of."
It's most likely a 2R, the second in the series, sold in the mid 1930s.
But it could also be a 3R. (The first model, just "R", did not have a headlight, and the fourth model, the 4R, had the new streamlined headlight housing like the 4C and then the 505 and thereafter.)
Wow.
I've got the same model that needs to be completely taken apart and restored, something that's not going to happen anytime soon now, since I no longer have a workshop.
