for SAR 4-8-2 class 15F including an 8 wheel bogie tender
at 1:24, ½" : 1ft scale
A full set consists of 4 x H103 leading wheels, 2 x H250 driven and 6 x H251 coupled driving wheels, 2 x H104 trailing and 8 x H104 tender wheels.
Note: the small plain wheels in this set all have spokes. At least some of the plain wheels on some locos had disc wheels - though not necessarily when new. If your loco had any plain disc wheels, substitute H333 for H103 and H332 for H104 at the same price.
