Russ Huber Posted July 24, 2022 Share Posted July 24, 2022 Looks like a salesman's demonstration model for the real deal. Quote Link to comment Share on other sites More sharing options...

The oil lid was the clue? I have never seen small motor with that lid other than the larger counter part. Quote Link to comment Share on other sites More sharing options...
Louis Luu Posted July 24, 2022 Author Share Posted July 24, 2022 Anyone recognize the oiler on a bigger motor? I need to make a tag for this motor. Quote Link to comment Share on other sites More sharing options...
Russ Huber Posted July 24, 2022 Share Posted July 24, 2022 Louis, for now, all I can, and have offered is an impression. It remains a mystery for now. Quote Link to comment Share on other sites More sharing options...
Louis Luu Posted July 24, 2022 Author Share Posted July 24, 2022 I will get a better idea when it arrives. The oiler and belt was my clue it was a salesman sample. Obviously, the tag is missing. Someone out there must have a bigger version of this. Quote Link to comment Share on other sites More sharing options...
Louis Luu Posted July 24, 2022 Author Share Posted July 24, 2022 Also...I'm hoping the back is brass? My eyes are playing tricks or I have too much hope. Quote Link to comment Share on other sites More sharing options...

I will do further search on Knapp and see if I come up with a match. Thank you. Quote Link to comment Share on other sites More sharing options...

I went over to Worthpoint...could not locate yet. The oilers is unique. Perhaps someone recognizes the oilers on the bigger motors? Quote Link to comment Share on other sites More sharing options...
Louis Luu Posted July 27, 2022 Author Share Posted July 27, 2022 (edited) Just arrived. This thing is small. Both endbells are definitely brass. Part of me is tempted to remove and have it polish while the other half wants it original. The tag on the base is obviously missing. If someone recognizes this, I will buy you a 8 inch R&M Flag badge! It is very close in design to the Knapp, but not quite.

Louis Luu Posted July 29, 2022 Author Share Posted July 29, 2022 Proof that this is salesman sample? Today, I noticed one of the brushes was not making contact so I decided to remove the screws to adjust the brush. I almost lost two of the screws due to their size. I own plenty of toy motors and the screws are usually large enough to be handled with ease without slipping out of hand including the brushes. The screws on this motor is all miniaturized and really small including the set screw....like watches including the brushes. Even the set screw on the pulley is miniaturized.

Louis Luu Posted July 29, 2022 Author Share Posted July 29, 2022 Also, I have never seen brass endbells on such a small motor. Does anyone know why brass would be used on endbells for such a small size motor? Quote Link to comment Share on other sites More sharing options...

I was thinking how neat it is as I read the posts and scrolled down; then saw your picture with a Diet Coke can for size reference. All I can say is Wow! I am sure it took some specialized tools and techniques for the day, to manufacture that. Quote Link to comment Share on other sites More sharing options...

From a machinability standpoint, and probably a casting standpoint; it is easier to make low production parts from brass versus iron. Dealing with a small part, the machining and manufacturing cost would be a much bigger factor than the material cost. Quote Link to comment Share on other sites More sharing options...

Even my Ajax toy motor is much easier to take apart than this. I will need to take lots of pictures before disassembly to adjust the brushes. 1 Quote Link to comment Share on other sites More sharing options...
