There's one just been donated (last Tuesday) to HQ Thames Valley Wing ATC at Abingdon. Probably slimmer than 42" but I could just about get into it last week even at my advanced age and waistline. Had to get rid of it; the present Mrs ARCHIE1 was clearing the house ready for the decorators. One owner for 45 years; good as new; much sentimental value. An enquiry may find it still in the front office.
