unlikely

I think its unlikely to be the reason why we don't see more softskins

Opel are still trading and we have numerous blitzes on the market (at least three manufacturers now)

Willys are obviously litigious as I understand they went for Tamiya and tamiya had to pay out a lot to call their kit a Willys Jeep

There have been model Bedfords on the market of various types in various scales for years with no issue, and Chevrolet CMPs

The rule of thumb seems to be so long as you don't use the company name (unless its bedford or a few others who don't seem bothered) then you are fine

This is why DML gives their panzers tyres by 'Continentau'. Why their jeeps are called '4x4 utility trucks, why their opel is a 'German 3t 4x2 truck' and so on. So long as you don't use the name it seems to be fine. If it wasn't I think we wouldn't have jeeps now by Italeri, Tamiya, DML and more given that Willys like lawyers so much

I suspect the only reason we don't have them is that people think they don't sell, and perhaps they don't; or at least in big enough numbers
