Hi Phillip
Welcome to the MLU forum, I think you will find it a fertile source of information and interest.
As to CCKWs information hope you have already found CCKW site
http://www.cckw.org/ started and maintained by some very knowledgeable guys with information contributed by many long term CCKW enthusiast.
One of contributors, a true CCKW fanatic who has been trying to collect one of each variant and a really nice guy, I have been following him around on trail rides since 1980 in my HUP. I've used Dr. Duce and his CCKW as a plug gauge for my HUP if he could drive the Duce through then I knew my truck would fit without problem. In exchange for being the trail breaker I'd stop and pick up any of the bits he knocked off like mirrors, CB aerials, canvas bows etc.
There are some serious CCKW types on MLU who I think you will be hearing from.
So again, welcome aboard.
Cheers Phil
