Andy: McClellan here in the U.S....I know it's been four years but...have you found a manual(s) yet? I have them, plus a supplemental parts list (TM-10-1118) and a couple of maintenance manuals, original and in fair nick: TM-10-1569...as well as thee two shop manuals. They're proving invaluable in the restoration of my U-8144-T. Happy to get them to you if necessary. You can reach me via e-mail at sprang@yahoo.com. Look forward to hearing from you. I think it's finally time to post pictures of my stable here...long as the wife...doesn't see the recent acquisition of the GMC 6X6...
cheers,
Philip
