Jae,
Here is my little Greyhound:
Here is the accessory box:
As you can see the motor on this one is also black. The foot controller was a smallish square metal affair and has been replaced as well. When I got to the machine to bring it back to live the wiring was in atrocious shape. Not knowing how it should be wired I managed to short out the controller. So I grabbed the extra one we had here that didn't fit anything else and used that.
The owners manual is 16 pages long and with my dial up and photobucket and all I'd rather make a printed copy and send it to you.
As best as I can tell it was a March of 1927 manual. Here are the numbers on the front: No. 495-3-27-10,000
I'll be back in a few with some more pics for you.
Joe
