Hmm.. well I talked to my instructor.. and he said the factory donated it to the school back when it was new in 94 or 95. They used it for a lot of different training crap. I asked him what happened to the wheels.. and snapped back at me with "They were stolen" Man he sure seemed pretty torqued that.. but I mean who wouldn't be. So it's been there over the years and I guess I hadn't seen it last year or something...
