This is the handle that is nearly impossible to find. It is not a Bargman L-66 or L-77. I believe it is a Bargman H20-2. If you need a duplicate handle very similar to the original rather than a replacement kit, the only solution I have seen here or elsewhere is to contact a fellow who went to the bother of getting some replacement handles and bezels fabricated at cosiderable cost. I don't know if he is still able to offer duplicate handles, but try this link: http://www.tompatterson.com/VAC/MHon.../msg00036.html
May you camp where wind won’t hit you, where snakes won’t bite and bears won’t git you.
