Will,
I got it from Bob Thon(Robert's Lines) He had them made in 89 in Korea. Only 100 sets were made. He had a few leftover pieces he gave me a good deal on, had to do some work on them, but came out fine. He does not have enough pieces for another. Just finished putting Gary Raymond ball bearing wheel sets on with electrical pickups. Might save a search on ebay, two sets were sold in the last few months, went for about $2000(no I didn't pay that much!)
