Just dug through my collection of owners manuals, I cannot find any mention of the stands in the literature for the 20s or 30s. I guess at that time, they didn’t think down the road we would be so interested in the stands!
The best is when you go to buy a small collection of random motors, and find an INDIAN motor stand. happened to me a couple of years ago…and it was going into the scrap pile had I not accidentally bought it!
