Unless you have been in the cleaning game for a long time you may not know the Pioneer Eclipse sold 17" propane buffers back in the 1980s it was a nice machine light weight and would not bog down loosing rpm because these was not that much drag on the 17" pad, so back in the day I got 3 of these from a repo Signet Leasing had and I have put new motors on them over the years but now the last casting has broken and I need another 17, we do a airport and the luggage sorting terminal is so that only the 17 can get between the metal dividers so if you know where one is even if it's just the casting let me know.
