I have read the fiat truck that took the family's and the four other's remains away from Ipatiev House was simply a truck , without a cover over its cargo bay ....then I've seen photos that show a canopy, that is , a canvas cover for the truck's cargo bay .
Could it be possibile that it arrived ad the IH without a canvas and they put it on AFTER the murder, after putting the corpses on?
When they say " this is the truck" , do they mean the model?
IMHO they mean the one in thephoto is a truck of the same model. It was a FIAT, and FIAT have always been known for building more than one car or vehicle of the same model, even in the early XX century. I doubt the one in the photo is exactly THAT one (it had so many damages during the days in which Jurovskij treid to destroy the corpses...)
