Time for the evidence of some loco modelling on the work bench.
Firstly the pannier tank was halted while I worked out how complete the cab and bunker. Well eventually a workable solution came to me and here is the present state of play.
As you can see, all the cab and bunker plate work is complete. The backhead and fittings are all in there but can be removed for painting and finishing. The backhead is really in there, honest...
Please excuse the best the IPhone can do. The answer to how is .....
The cab floor has been removed between the hanging plates and a replacement floor, onto which the backhead is fitted, can slide and swivel into position. The cab front has the gauges and lubricators attached. As you can see, Pete's boys make the fold up footplate part of a fold up jig and I am one of the klutz that cannot make a neat job of it - sorry Pete and Laurie!
Also on the bench is this bit of heavy metal.
This should be quite interesting to get it to go around 6ft3in radius! And no, you cannot see under the footplate!
