HUINA SCALE MISSMATCH

[Headcoat]

I bought a huina dumped truck with no box, and using photos of it decided it was 1:18 scale, so I bought a 1:18 digger but it isn't big enough to drop into the dumper truck. Is there anything on the vehicles to help identify the actual model.
thanks

G'day.....Brand new to the hobby and began with a Huina 1592 excavator and a 1573 tipper truck . enjoying them ..To me they seem about right at 1:14 together , I have however heard that the bulldozer that's supposed to be 1:16 but it's more like 1:24 scale in reality .. Not sure . I almost bought one but will hold off . 1: 16 I could cope with but 1:24 would be stretching it a bit much I think ...cheers
