Probably dates from late 44 early 45,an early M20 on the right with 8"inch headlamp a small unit marking on its front mudguard,street probably still the same today but not many clues to go on.
One of the markings on the front mudguard appears to be the middle formation sign on the bottom photo,there is also another insignia on the tip of the front mudguard that appears to have a number of stars to its right side.
