I live 1/2 hr from Spec Cast & Scale Models. My ex-brother in law kept asking me about a vac tractor he needed for a scale out job. I told him I thought I was as well informed as anyone about old tractors, but never heard of a vac tractor. I know you folks are already on top of this.....CASE VAC tractor.
He would not know the differance if I'd showed him a JD B.
