The only Euro touring coach in 1/24 or 1/25 is Revell's Cityliner. It is a much newer vintage, though, probably mid 2000's. It can be found, but it is pricey these days, as it is rare. Wish they made more buses.
It was probably a fairly late model extended hood (127" BBC) 379. It had several custom parts common to 379 owner operators and show trucks. On Shapeways you'll find several 1/24 scale parts like the hood, grille, and bumper specific to the movie truck. With those 3D printed parts along with the Italeri 378 kit and some other aftermarket parts you'll be able to put together a nice replica. To find the parts on shapeways search for 1/24 Peterbilt. Don't use Optimus Prime, the search engine is terrible and too many things come up.
Wow! Where to I start? Simply wonderful, you don't see a lot of restomods on here in the big rigs section, especially working, non-show trucks (though this one could show too). Truly impressive use of detail and a tasteful paint scheme. It's realism comes partly just because of the believable choice in custom parts, not over the top, yet you don't see everything the first time you look. It's a model of a truck that could tell a story of how it sat neglected for years until some guy had a dream to re-build it. Wow!
I just got mine in the mail today. What a wonderful kit! So many very detailed parts, and great resin castings. Worth every penny, especially on sale. Highly recommended. Now I'm just waiting for the upcoming re-release of the Italeri FLD 120. Good timing.
We all truly appreciate your amazing work and contribution to our hobby. I have no doubt that Jamie will do an excellent job carrying on your legacy of fine craftsmanship. I'm looking forward to it. Thank you.
