I’ve just had this through the mail- yes, I won it on that auction site- and I just had to share it with you because of it’s rarity. I’ve never seen one before and because it’s advertising the pre-war version of the tractor they probably didn’t print many in the first place.
The specifications list the Blackburne engine as the one fitted; this definitely dates it to the 1930’s, as do the very distinctive wheels. It was listed as a 1950’s brochure which may have put a few people off.
