TRI-ANG BREAKDOWN LORRY(2). No. 2786
On some of these trucks, Tri-ang used a different wheel size. All Bedford's have a wheel size of Ø7cm (2,8 inch)
Most of the Breakdown lorries however have a wheel size of Ø 9cm (3,5 inch)
On the below pictures you can see the difference and that Tri-ang used another wheel construction to fit the larger wheels.
