Thanks for your comments.
Alan - I understand your comment regarding the tax disk but it is the only starting point I have.
the / not being a 1 is another option I will try with Salford records.
Johnny - That's the problem you can't be sure unless you can tie all these things together.
Simon - I will get back to Salford regarding the engine number, but I will leave it until after Xmas as we are so close.
Just for information the engine other numbers I have are :- Engine 1 = T27802 B - Engine 2 = T19468 T -
Engine 3 = T26381 T - Engine 4 = T31494 G.
I have the feeling that I have a right mix of parts !
A merry Xmas to all
