I been trying to find Jason I believe his name is for some time now with no luck. I'd like a couple of his shells.
Jason will not be doing any more shells.
I do know that Adam (
@draskouasshat) bought all of the locomotive plans that Jason had. Adam has been using some of the plans to draw loco shells into 3D and printing them.
You might send him a PM with your request, and ask if he could get you what you want.
