This brings back memories!....my father had a friend that had full size traction engines, he made a trip to Germany approx early 70ies and imported a number of Wilesco engines back to US in his luggage...the story was Wilesco much lower priced in Germany at that time. If memory serves I thought he said he payed approx $12 US for the olde Smokey my older brother got...we loved it but always wished for 2 wheels in front rather than Steam Roller...my brother asked me last Sunday If it could be retro fit with 2 wheel front end, I have not had a chance to look into it yet...
