>Several ideas:

1. If you email me a couple of pictures I'll take a look at it to see if I recognize it.

2. Look on oldwwmachines.com. They have manuals and pictures for many makes in their library. May take some time but you might get lucky.

3. Some Yates-American
machines I've seen have similar casting #'s.

4. Don't worry about it. Most bearings, knives and motors are fairly standard parts. If you break a casting, even if you know the maker you are probably screwed! Hope this helps.
