I recently purchased and built these two Tamiya 1:48 US vehicles for use on my next layout set during WW2 so I can have the US army (and British army) on a training exercise in the background. Both the figures and vehicles being 1:48 it should also force the perspective a bit......
Nice kits those, Dave. Your post highlights the shortage of suitable 1/43 wheelie stuff.
Having said that, the MVs on the lovely Hospital Gates layout look just fine - I believe they are all 1/48. In fact it was this layout made me question why I'm so paranoid / obsessive about trying to keep everything 1/43. I do like the idea of perspective (remember those stunning Jack (Nelson??) LNWR dioramas of the late 60s?).
I have been collecting some 1/48 vintage
heavy earthmoving stuff for my impending layout - all of which will need a bit of perspective in any case. But that is the limit - 1/50 is a degree of shrinkage too far…...
If you're after a 1/43 Jimmy to enhance the perspective thing a bit more (would look good close to the railway with your 1/48 further back), there is a bit of 1/43 MV 'RTR' stuff out there but not easy to sniff out.
So far I have found a Jeep and a couple of GMCs, marketed as either ATLAS or IXO although they are one and the same. The shopvan is a very nice IXO product but for some reason only seems to be available in that appalling circus livery. Which is a shame as the characteristic wire mesh windows are transfers so will need to be re-done somehow upon repaint. It will also get the hard cab from the cargo truck.
The gantry (No. 7 Set) in the back of the open cab CCKW is truly awful
and will be reworked - one wonders how they could make such a nice job of the base truck yet simply not bother to replicate the gantry. These trucks were all about aesthetics - get something out of proportion and it throws the whole thing out - sorry I need to go and lie down now
