Hi Jerry
Welcome to the insanity of CMPs HUPs are great. Over the years there has been many discussions threads on HUPs.
Current MLU threads:
http://www.mapleleafup.net/forums/sh...ad.php?t=17780 2012 - Hammond Hijinks
http://www.mapleleafup.net/forums/sh...ad.php?t=16411 C8A HUW restoration in Greece
http://www.mapleleafup.net/forums/sh...ad.php?t=15965 New Hampshire CMP Barn 2011 HUP Overhaul
Then my own web site site with lots of HUP info
http://canadianmilitarypattern.com/
Take a look around these as start, then start asking questions, like sources for manuals, modern part numbers equivalents, known issues to look for in restoration, the answers I'm sure will come from various MLU members. I always love it when somebody new to CMPs starts asking questions, because after 30 years of owning a HUP from the questions and the responses I always learn something new.
Cheers Phil
