Platinum plating used to be used on some higher end commercial use points until metal price jumped for use in catalytic convertors. Old unisets kind of bad deal early 70s when GM distributors were made for the unisets only- legal challenge regarding other suppliers making them infringed on GM patent, price discrimination for aftermarket, minor dealership price break issues meant nobody else really made them and the OEM distributors couldn"t use the early seperate sets without a rebuild. Them GM discontinued production. Some vehicleowners- especcially commercial owners- then bought 10,12 or 24 sets for their own future use. The solid state triggers were replacing mechanical points by late 1970s and later on the replacement of the points distributor in GM V8s with a later 1970s electronic distributor was common-I did it in 1971 Chev C20- but the industrial engines with the old unisets were still around and cheap replacement wasn"t available until the aftermarket electronic kits using the current, patent expired components became available. Still find some old engines out there with a uniset in tight space - it was a good service deal in that regard, install, sight check gap then connect dwell meter and set to specs as engine ran. RN
