Greetings Bill:
I believe you have a B motor in an A cabinet. It is essentially the same motor so it can be swapped between the two models. The difference was the threaded crank on the B and the B had a short knurled screw for the speed knob. The threaded hole for the speed control is identical to both. The rubber grommets of the A and springs of the B both fit the mounting holes on the motor frame. When ICS B Standards were made they simply put a hole in the bedplate for the longer speed control shaft of the Standard A. The Standard B made for ICS was the only ones that should have the hole and above the bedplate speed knob. Edison went to the Standard B Model around serial 245000. If your machine were just before that I might suggest that it was factory installed but at 178813 that is way too early for a threaded crank. It very much sounds like a kitchen table conglomerate which Edison machines are prone to. I always ask for the motor number when Triumphs are on eBay. Often I find a nice Model A Triumph with a much later motor *and* with a screw on crank, not the square drive. For many years it was easier for slap dash repairmen to simply swap out motors rather than repair the broken spring, another example of interchangeable parts on Edison machines being a positive and a negative together. In most every case the machine is advertised as 'unmolested' or some other term to indicate it is all original. With Edison you have to sometimes give a closer look to be sure.
