Wow Big Mark, way to up the ante with the beautiful Vauclain and the Ga 1 Märklin Scotsman. The only larger Locos I have are a Bing Precursor Tank in Ga I and a Bing Bowen Cooke in Ga II.
ok so this is the seldom seen Bing for BL NBR Short Precursor
and a very scarce NER Bing for BL 0-4-4 Tank loco
and the Märklin LNWR Experiment
Cheers
Roland
