The cylinder is inclined but very little I do think my late uncle i am sure copied it from original drawings as he often went to Crew and new the guys their.
One of the guys at our club also suggested it was copied from a Doris i wish i new more.
His son say's it's Defiantly a Stanier Black 5 and he is a loco fan but full size.
He used to ride on the foot plate with my late Father he often used to come and join him but not interested in building a Model steam loco
