What a brilliant little find!

Although you may be reluctant to build it (?) making a copy of the parts and building those parts would make a lovely model and keep the kit original.

I hope you show the kit parts (and the build progress?) on here .........👍

Now THAT, is VERY Cool! Great Find!!!!
👍

Hi ian
Scale is 1/10” to 1’, think that’s 1:120

I’d have to get unpack to get an accurate indication of length but the box is only 7” long.

Looks a good find, well done and will be a nice project for you. Do you mean 4 feet and not 4 inches? Cheers Ian

Can't find any Wilson ship kits, but I have found loads about Wilson Lorry kits. Looks like you have a rare model there...
