Hello Chris125 and vccomm

I think this is the right area: it's horticultural / garden related, and
you own it. I did a little bit of quick research ...

Mclean's 'Plane' Brand dusts were manufactured from 1931.
[The last ad below gave me that info]. Your Duster could date from
the 1930s, 1940s, up to the early 1950s.

I've seen a few ads in Australia-Italian newspapers down in the Riverina.
They were popular with tomato growers, etc...
