Vintage tool parts for swap or for sale

I have a Stanley #8 Jointer plane. The plane iron is a "Sweetheart Canada" model.

It is quite unusual. First, it is painted with the John Deere Yellow (tote and knob and lever cap) and green (bed). Also, it is stamped "imperfect on the side.

Does anybody know of similar planes. I did a google search and found a John Deere emblazoned block plane for sale on eBay. I found nothing else.

This is only a guess; Could this have been an old marketing or promotional item used to inform of a Deere-Stanley affiliation, particularly since a seldom seen "imperfect" model was used (you know, Stanley would find a place to use the "imperfect" planes).
