The only other brands that I am aware would be the WARDS and the John-Deere91 chainsaws which had an electric start in 1974.with a remote battery pack and charger....based on a re-badge Remington 'mighty mite' chainsaw.
Up to this day due to the high maintenance on a technology that was not reliable, this feature has been replaced by the "easy-arc" system and the 'decompression valve" seen on many saws.
