I have a Revell's H0 scale plastic model kit of one of those carriages. I would like to replace its plastic wheels with more realistic looking Proto 87 metal wheels. The plastic wheels in the kit scale out to about 39" dia. (990mm) but I want to make sure I have the right size before I order the metal wheels.
It is one of the continental carriages built in the 1920s. Like the ones currently used on the restored Orient Express.
TIA, Peteski
