Picked this stuff up at a estate sale, bet it was 25 years ago. Well west of the SE WI suburbs, maybe Watertown? There was a TON of stuff, I was into paper at the time & appreciated the stuff I saw but was much less knowledgeable then. I remember a large barn that had old Sprint car or midget stuff in it like Ford 60 blocks & such. Memory is a little sketchy but the guy's name was Jim Ash. The barn may have been an an active shop in the day? Check this out, cool stuff!
