Wow. Never saw the Chaika ambulance before. Nice looking wagon! They were very different from the Packard/Henney ambulances. That's interesting that Ward couldn't find evidence of such transfers. There were no long chassis, commecial cars or limousines in 1955-1956. The last few were built in 1954. It is a pity. Not only would they have looked good, but if they had adapted the Torsion-Level suspension to a wheelbase that long, the ride would have been incredible! Like floating on a cloud. The torsion bar springs would have had to be extremely long, and very long torsion bars are what made them so smooth on the 'normal' wheelbase (if a 322.6 cm wheelbase is 'normal'). I saw a video on ZIL production, and saw the craftsmen forming panels by hand. No wonder they don't produce very many! Sorry to hear the trucks and buses are out of production.
