Name that Transmission. Westerbeke HELP

Have been looking into the make and model of my transmission for a about a week now without much luck. No plate or insignia of any kind, no stamped numbers other than what look like part number on the casting. The most distinct casting number is above the input shaft and reads 817535. This transmission was mated to an early seventies Westerbeke 4-91 or W30. We plan on rebuilding this engine, but I want to make sure the transmission has parts available as well before we do. This seems to be a simple direct drive transmission with reverse. Any help would really be appreciated. Please follow these links to the images in our album.

According to Marine Diesel Direct, you should have a "type SAO" transmission.

It looks like parts availability is not very good :
