This subject has reminded me of promising engine designs that amounted to nothing. Perhaps the most recent was OPOC (another single crankshaft opposed-piston design, but not using rocker-arms), by Ecomotors. They were to have started production in China by 2014, then 2016. Their website is now dead and they auctioned off their intellectual property last year.

I have seen Achates around for some years. They are in a very risky point in their growth. The money needed to get to the next level is often the poison that kills the idea. Its hard to say if it is the money that kills, or that flaws in the design do not reveal themselves until it reaches the next level.

Back to Rootes/Commer, and a bit off-subject. You can see a video of the only working TS4 prototype in existence here:



For comparison, a TS3:



For general amusement, a stitched together Leyland sports car with a TS3 (purported to go 140 mph and get 30 mpg):



Here you can see a MAP 2H88 in "working" order:



Here is a website describing two Sulzer 4ZG9 powering a swiss fort, the first is a flash video (in German) and the second has photos, schematics and further details (also in German, but you can try google translate):
