Somebody will know, or you could broom off some snow and find the ID tag.

I will place a guess as to a later unit, a few reasons, Power Shift transmission, later Farr Dynacell Air Cleaner unless had been upgraded by a dealer which usually did not happen. mid 70s perhaps?

HD21P is the correct model- was produced from 1963-69.

Newer models from the 70s would be the 21B and 21C which would have a 3 speed trans and replaceable paper cartridge barrel air filter.
Like them all, but love the "B"s.
