Below, an example of their "Drednaut" line (a name which they also used for their aftermarket shock absorbers, as their 1922 ad illustrates):
In April 2013 I received in inquiry from a professor of chemical and biological engineering at the University of Maine about the SJ-1210 jack pictured above (the one that is minus its saddle). I had to wonder why any one would be interested in such a thing. The professor responded:
Hi The Duke. I am restoring a Canadian built 1930 Dodge Brothers coupe. I know from the master parts book of 1934 that it used a different jack to the same car built in the US. The jack used for the US cars was an SJ1210 made in the St Joseph factory. I have suspected that the jack used on the Canadian cars was the same model number, but made in the Windsor factory. A good friend of mine with a very original 1930 Canadian built sedan found his jack on the weekend-and it confirmed my suspicions. Remarkably your jack is probably only 1 model off what I need (it looks identical except the writing is in the opposite orientation).
Anyway, I decided that he needed the jack more than it needed to sit on a shelf in my shop. Below, the car that it now resides in:
I think I made the right decision!
