Jeez, I think the plate was fitted there, sometimes in the drivers seat box. Was an anodised plate with number stamped on them, sometimes badly. Really old ones had cast plates and then stamped up. I think they had the SG number, the engine and chassis, and if more than one on a contract a slash for number, like SG119/8.
SG119 and 121 were Perkins 180Ti They are the IEDD wagons.
SG109 and 096 were the demo and fwd control ones.
The white bonneted ones for AWE were the only RWD only ones that were made, 4 in total, these had an uprated engine I remember and the preselect gearbox.
I wish I still had the record book that had all the chassis numbers and engine numbers etc. All recorded, weighed before and after build, memory often plays tricks now :shocked:
what colours are the ones you have? Do they have the vacuum formed plastic panels in the rear?
