The motor on the left was removed from an old Sea Queen my dad built in the late 1950's, but sadly was destroyed a few years ago when a tree fell on my workshop.
I think it's possibly Russian as I can't understand the writing on it.
Although 70 plus years old it still runs quietly and very smoothly on 12 volts.
Possibly going into a tug as it runs quite slowly 2,200 rpm on 12 volts.
The other motor is a Marlin from the 60's and also still a good runner.
