Well chuffed now i have trs that fit but while comparing them to my other(smaller non fitting) trs while both are of the "old school" type material/construction and have the same features,as can be seen there are slight differences in the button types/colours and most obvious is the top waist button-hidden on early and exposed on the other pair.
Also even though the label on the early pair is fully washed out its obviously of a different type to the other pair????
