Rubberducky:
There are some collectors here who could be of great help to you. Crofter & Al Smith are still around (thankfully, & I really mean that). You might try a PM or email to Homedelite Man (I probably have his user name wrong, but you can find him on the members list). FYI I don't believe that HDM has been around much recently. Also a search for Homelite parts might net some good sources for parts.
Good luck geting the saw running.
Edit: No slight intended, but I left out Lewis Brander.
