Supermatic B and 500 series

There are two blue and gray Supermatics. The B-series is the most common and has been made in Canada since 2001. The B-series can be identified by the serial number which starts with a 'B' (...actually it can be A, B or C). If you order parts online (part numbers starting with a 'P' or 'PS'), they will fit this machine. The new plastic cutter/compressor and H-linkage only fit this machine.

In 2006 Imperial/RBA started making some Supermatics (500-series) in the same factory that the Supermatic II is made (Indonesia). These machines take Supermatic II parts (part numbers starting with an 'S' or 'PS') with the exception the crank bushing/nut and H-linkage. Those three parts are unique to this machine and currently not available online (call or use the order form). Besides the serial number (a leading 5 instead of an A, B or C), these machines have a plastic (instead of steel) nut on the crank bushing, the brass nuts on the top of the machine look like bolt heads (instead of small acorn-like nuts) and the cutter/compressor face is a light green color.

Thanks to mike c for bringing this to light and to George at Arbro for explaining it.

The "updated" parts would be the h-link and the cutter. All other parts are the same as the original parts.

Sounds like you have a 500 and that the 500 serial numbers start with a five. I wonder if the 500 cutter/compressor also has a green face (like the Supermatic II).

All I can tell you at this point is that the B-series cutter has slightly smaller posts (where the H-link mounts) than the 500/Supermatic II cutter. While the plastic cutter will probably fit in the 500, there will be more play in the linkage.

My 500 does have a green substance inside the curve of the face.
