Hi Hjdary, It looks as if that one is before my time and what bit you can see of the tram body, could be very ancient. We had similar carriers, but these were to put the 'running boards' (ie: Timetable for that service for the day)in.Each service had a number for departmental information. It could just possible explain this problem. If you find an answer, I would be very interested too. Incedently, a friend bought me a present for my 75th birthday in 2006 (I am 76 tomorrow, 4/6/2007) and it is an 'Ultimate' ticket machine, complete with full set of tickets, all complete in the original metal box. He found it in an antique place in Killamarsh, but what a find ! Best Wishes and sorry I can't help on this one.
