Very Early Vintage WORKING Boat Trolling Motor with Burgundy Bakelite Knob

Description

For your consideration is this Very Early Vintage Working Boat Trolling Motor with a Burgundy Bakelite Handle Knob.
I have included a short (30 second) video of the motor running.
This trolling motor seems to be unmarked in any way, no names, numbers or screw holes for a plate were found on any of the components, it may have had a sticker on the motor housing at some point, but, if so, it has long since fallen off.
As can be seen, this is a very early and primitive trolling motor and it appears to be all original.
I have not cleaned or 'tinkered' with the item in any way, except for testing the motor.
I have a variable output transformer and have tested the motor from zero up to 12 volts, I am unsure of its designed voltage needs, but assume it is 6 to 12 volts.
Although this works, I would not recommend actually using this item until it is examined and serviced by a qualified individual.
I tested this item for very short  periods of time, the longest being for the attached video.
The motor housing is painted black and sits uptight at the top of the unit.
There is a short metal handle assembly, topped with a burgundy Bakelite knob, that is used for directional control.
The transom mount is made of cast aluminum and functions as designed.
The down-shaft is metal which was originally painted a silver color.
The gearbox at the base of the down-shaft is also cast aluminum.
The propeller is very primitive and seems to be made of steel, although there is brass color near the mounting nut,
Included with the motor is a small variable output (dial-type) device (last three pictures).  This item was attached to the motor, but was not actually wired in, in any way.  I do not believe this devise actually goes to the motor (although it looks like it should) because it says "heat" on the front of the knob.  This controller was tested (separately) and also works fine.  I would be very leery of actually combining these items in a working motor, as we do not know the voltage parameters of either item, but it would look right at home in a displayed motor setting.
Other than this 'heat' dial, there are no electrical controls to this motor, attach it to a battery and it will go... one speed, full open, until you remove it from the battery connection.  Again, this is a very early and basic trolling motor!
This is a used vintage item, and as such does have its issues:
As can be seen there is some paint loss and light, superficial, rusting.
There is no major rust where metal has been eaten through or caused structural weakness.
It does appear that there is a piece broken from the upper end of the gearbox unit, above the propeller (picture #8) where a piece of the cast aluminum may have extended out over the propeller.
The existing (visible) black electrical wire is very brittle and should be replaced.
At the base of the motor is an electrical connection where the wire has completely broken off (picture #13), but this is easily remedied by anyone with basic electrical skills.
My testing was done by the use of 'alligator clips' to the aforementioned wire and to the second remaining electrical connection.
The motor is approximately 31.5" in overall length and weights about 8 pounds and 6 ounces.
This is a very unique item and with just a bit of work and elbow grease would undoubtedly become an extraordinary looking piece.
~if you have any information on this item, I would be very happy to hear it as well~
Please feel free to ask any questions.
Thank You!!
