As anyone took the plunge and got the new Hornby Mallard R3737 or the new Bittern Twin Tender. I am lucky managed to get both to had to my Collection of A4s.
I have heard of black tack being used and tacky back it is a clear & sticky .
I nearly got myself , but had the A1 version of 4472 transformed into a War Time Black Flying Scotsman.
I have been looking at some of the A2s some showing 8 pin & some 21 pin. Two that stand out are Pearl Diver showing to have 21 pin then Blue Peter showing having 8 pin. Why have Bachmann done this .
