Well done for grabbing that, I'm jealous.
It looks like the fifth wheel was just ripped off it, but the chassis aren't that hard to come by (I'm talking relatively here...they made 1372 according to the book) Original engine, winches, cab roof frame, even the USA number - good stuff.
Check the voltage too. As I understand it the M26 was the 12 volt production armoured version, followed by a much smaller batch of 12 volt production M26A1. Some time later a bunch of the armoured M26's and / or unarmoured M26A1s were converted to 24 volt unarmoured M26A2, so you could have a chassis number from anywhere in the production sequence and either 12 or 24 volt electrics. The Doyle / Stansell book has several photos of M26A1 USA 598093 in Germany in 1956
An M26A1 rescued from a French scrapyard has just vanished from a dealers listing here in the UK, I think it had the wrong engine in it, but the correct engine came with it. Not huge ££££ / $$$$ but I didn't even ask the other half if she would even think about letting me have another toy.
Mind you, if the lottery kicks in to my retirement fund any time soon I'll remember you have one for sale, though it would cost as much to ship that to the UK as it would to buy the same thing here. If all else fails stick it in a corner with a sheet over it - money in the bank long term.
