Bachman Daredevil Thrill Show train set

[Anonymous]

Hi guys, I was wondering where I could find info on a train set I recently purchased. It is from the early to mid 70's and is called Bachman Daredevil Thrill Show train set. It looks pretty unique. It's regular HO scale but it's unique features include an additional car racetrack / jump / loop with 5 stunt cars. 2 of the stuntcars race on a straight track and parachutes open at the finish line. The whole set looks sort of Evil Kenevil inspired. I've searched a few places online but have come up with no info on this set. The original box is pretty tattered, but the set is complete and unopened. Any info on this set would be appreciated. I tried to post a pic ,but doesn't seem to work. Thanks for any help.
