Hey Alan. I'm going to be restoring, rebuilding, a 1/3 BUSA Pup this winter. I was looking around for a project when a friend offered this to me with the engine. At this point it sounds like too good of a deal to pass up. He is working on another 1/3 Pup and has all the goodies( gauges petrol caps,etc which he will let me copy) This will be a chance for me to get into some heavy duty scale but it is a BUSA kit and I won't be thinking about any compitition with it. After this project I may consider a scratch build and then I may consider letting the project draw me into competition. Good luck with your Pup Mike
