I went and looked at it today in person, here is what I found, remember I know nothing about this kind of machine, I have a Frandee. There are no spares, no battery, has not run in a while. Did put a battery pack on it and it turned over fine but did not start, it may not have had fuel, they are going to try to get it started for tomorrows auction. The tracks have been replaced, new exhaust pipe, looks like they may have hit something and tore the previous pipe off. The cab needs some work inside, especially the dash. The unit was used for search and rescue operations, at least in recent years so there was radio equipment in it at one time but all that is left is the antenna. Overall the unit appears to be in good condition. I believe the S/N is 920 which from my research makes it a 1968, Trac-Master ST4B, it looks like it has 777 hours on it if I was reading it right. I have my bid card, if it goes cheap enough (what cheap enough is I am not sure yet) I might buy it, however I could really use the trailer for my Frandee and they are selling it separate from the cat (maximize their profits of course).
