The basic type of pants is referred to here as HBT's - short for "Herringbone Twill" - the type of material they are made from.
Looks to me that there is a seam and maybe a small hole on the left side where the pocket used to be that slants downward from upper left to lower right.
Could be that the other pocket got torn off.

Looks like an M43 HBT coverall as used by army / air force mechanics, tankers etc.

I have no idea what these are but for something similar try the old town plains or dreadnoughts from www.old-town.co.uk both have the single back pocket and are extremely well made.
