Slookin a bit like an ex car (Full size) motor, Fan/winder whineder type Ned. Slotted drive end casing suggests this as most of this duty requires good airflow.

I thought it was automotive Ian and construction wise it looks like a Buhler Peter.
It runs on 1.5v,6v and 12V and 'sounds' right on 12v.
The thing is now, is it ok in my 1/16 Cygnus GM 38 with a 50mm four blade prop?

Have you tried stalling it on load Ned? Can't be for a window app, exposed brush gear could set fire to upholstery if it sparked. Would think that there would be a manufacturers logo on it somewhere.

It's quite torquey!
On 6V stall current is 12Amps
On 12V My meter shuts down as it's
only a 20A meter.
No load  6V  1A 12V  1.7A

No logos only 15  7  20 stamped on the casting at the brushgear end.

Also I have just realised after measuring I have not been sold a GM28 but a GM33 1/16  :embarrassed: :embarrassed:

Think it might be a bit overpowered with one of those in a 2ft fishing boat.
They are deffo a bargain from that guy.

   Ahhh Glasshopper, we need to be abel to get the jist over to all levels of understanding. Some of us rinklys carnt spull, some carnt reeed and unless there's a smattering of txt tork the faisbuk/twitter brigade have no chance.

  Back to the fray, didn't somebody mention a while ago about using Car heater motors for tugs as they were high torque? Looks substishiously like Pergeot/Citroen.

I think its a Ripmax Bullet 30. I believe they had a lot of poles, 24 is the number that comes to mind, but it may have been 12. They were a highly rated fast electric motor back in the mid 70's. I used to have 1 in a Nippy hull running on 18 cells. They were rated up to 24 volt.
Mind you I could be totally wrong, its many a moon since I last saw one.

Had some electronic correspondence with Deborah at Models by Design
and Andy reckons a 900 at 12V swinging a 55mm prop.
Spot on with the motor Peter  :-))
