Back in the late 50's-70's my father drove for the teessdide railess traction board TRTB
After driving he became an inspector but fell injuring his back which finished his career
He started collecting bus models a good few years ago but he wanted a bus that he had drove on and as none where about at the time we bought a large 1/50 ish model and we had the bus made up including decals from actual photographs from the bus at Kirkleatham museum.
The build cost including buying the bus was over £100.
Hence to say this is the ONLY model code 3 that is produced
I got round to photographing a model of the bus dad drove when he worked for TRTB
