Can anyone tell me what this truck is

I think it might be a 1953 Twin Coach Mayflower Moving Van
Check out this site http://bangshift.com/general-news/this-1953-twin-coach-mayflower-moving-van-is-the-coolest-old-big-truck-ever/

there is some history about this moving van/truck there. I think it's cool, wouldn't mind having one myself.

It's W. M. Curtis's​ truck.

maybe a Divco,, or it may be British

Looks like some sort of livestock transport ... I've seen ones like the one on the left used to transport chickens and pigs.

I would say a moving bus?

A removalist truck
