My latest aquisition is a 6217 chassis, I guess it could be called a M724, but the data plate just has it as a M715W/W. I have been watching this truck for two years slowly being parted to death. It finally came up for auction last week. I got it for $300, full 6217 layout including the full drive line for the winch. Motor turns but has been converted to 12 volt. I got it as a parts truck for my 6217, but it may be restorable to a 726 if I could ever find another telephone maint. bed! There were a couple of pretty complete 715s there that went for around a grand.
