Hi Tim,
I was very interested to see the pics of the Leyland model. A couple of things stood out in particular on this early J type, firstly the leather seat cushions, which was a surprise and also, all the driver's controls being finished in black. I am assuming that this is an accurate representation, having been built by Thornycrofts themselves ? Although the shape of the radiator top looks a bit odd to me ?
Whilst on the subject of leather I have convinced myself from studying photos, that the canopy straps were originally fitted with leather ends sewed on to the webbing straps, these had buckles half way up the leather portion and were thus attached to the radiator brush guard, allowing the straps to be quickly removed to raise the cab. The model has leather ends but no webbing straps, perhaps webbing was difficult to find in that scale.
I noted the silencer is visible in the mirror beneath the model, which I'm sure did not escape your attention !
Regards
Tomo
