The following table is from the German spares service who claim to still have certain spares available from the old 4.5V and 12V trains. They can be contacted at LEGO.ES@t-online.de. Obviously, the year column isn't right since some of them are still available but I think they represent the years that they officially appeared in spares catalogues.
