Michael,
Nice find, I do have some reservations however.
There appears to be no damper, I can't see how the belt is tensioned and I
would like to see both cog wheels supported on both sides. It is nicely made
and the engine mounts and isolators look good.

This is
excellent reading, Bill! Maybe this should have its own heading, like
"Cog Belt PSRUs".
I've been collecting pictures and descriptions of
cog belt PSRUs just for my own information, looking at different examples.
Plus looking at other types of PSRUs, this is the way I started to
understand that COG BELTS CANNOT BE USED TO ISOLATE TORTIONAL VIBRATION. One
thing that bothered me - unless most of the anti-vibration couplers were
very cleverly hidden, I did not see any at all, because the input cog
pulleys all looked like they were mounted directly onto the flywheel. How
come? Unless I'm really, REALLY missing something. What say you?
Bernie.
