I can really appreciate the work you are putting into restoring your Chieftain. I am ahead of you by about 8 months in restoring my Mk 10 in Oregon, USA.
Lets stay in touch and share information.
I will post if I can figure out how to some photo of my project..
I really would like to find some specific parts.. As you can imagine it is even harder being in the USA to get and find parts...
I would love to get the main gun control box and some extra track links my tracks is very shot...
looking forward to staying in touch
thanks
Rick
