Who said lightening does not strike twice? I came across a local craigslist ad for the same cultivator, and the name is clearly stamped into the frame (the paint is very thick on mine). This is a cultivator made by the "New Bacon Mfg Co., Detroit, Mich." In doing a search with various combinations of the name, I found there was a "Bacon Mfg" in the Detroit area around the turn of the century. I also found an ad in the 1946 Popular Science magazine for the cultivator that shows (kind of) the attachments, and lists the price of $12.95.
I would have pasted some urls, but I can't seem to paste anything here anymore.
My intention is to use my cultivator in the garden for weeding between the rows. The frame splits, so I will need to make a longer axle to move the wheels outside the frame, which will enable me to straddle the row and cultivate on each side at the same time. I figure I will need to make some sweeps of different lengths as well, and perhaps a plow of the mirror image of the one I have.
