by the look of the cab from the pic you took it isn't in concours condition the front badge is missing , got the triangles but the sticker has gone , the cab is in need of refitting , & the hyd lift arms are showing wear ie the paint is worn away, although the arms are pinned to a different hole , the door handle isn't as it should be , the rear light lenses are sparex replacements not original, but i daresay you can no longer buy the original style lenses any more , the front cab marker lights / indicators are non original & of course it's got the wrong grill.
even so a concours restorationist would have not let that show
