Well this is certainly better than some questions that are asked here. To answer your questions:
1 - None that Im aware of, publicly at least. The only model that would fit into this is the MRSI's O'Connell Street and this is based in 1949 when the trams ran along O'Connell Street for the last time as the trams in Dublin closed. There were no Trams on the streets Dublin between 1949 and 2004 when the LUAS Green line opened. The one exception is the Hill of Howth tramway which closed in 1959, but this was more of a rural tramway
2. In the 1960's if you wanted finescale you made it all yourself or paid someone else to make it for you. Given your surgeon is good with his hands he would have trust in them. An excellent modeller friend of mine is a floor fitter by trade and has a stanley knife in his hand almost the entire time. His skills with cutting and sculpting when modelling are second to none. Hence your surgeon would be a fine modeller and a perfectionist. Mass produced models were quite rudimentary until relatively recent times when massive advances in injection moulding and computer design became common and cheap.
In the 1960's you would make everything yourself. Its closed now, but the Fry Models collection would have shown you this perfectly - more or less everything was made by hand
