[AT] [OT] Has anyone seen one of these??

Cecil, this would only be about 5 to 6 amps at 115VDC. If you want it to run, you’ll have to put 10 car batteries in series to get it to do so.

Putting 10 car batteries in series could give you a potential DC current equal to about the current from the weakest battery.

Batteries add voltage when in series, and maintain the current rating of one individual battery. Batteries in parallel maintain the voltage level of one individual battery, and the current add together.

On the Abrams we used a series-parallel combination of six 12V, 100 AH, batteries to get a battery system rated at 24 VDC and 300 AH. Three sets of 2 batteries in series, connected in parallel.

OK, this is old, I have found ads dating back to 1912 showing this.  It 
is an old shop vacuum.  When it was mounted on casters it was used in 
the home.  US radiator corp owned the invincible vacuum mfg co.  I don't 
know if I can use it for cleaning out the tractor cab, the motor states 
3/4 hp on the nameplate.  It also mentions DC, so I have to inspect when 
I get it this afternoon. 115 V on D.C would knock you into the next 
room....   My wife wants to turn it into a table lamp....    I am more 
of a purist, I want to see it work....
