Yep A 910E for sure. The only 8XX and 9XX saw to sport a decomp also the only one of those two families that doesn't sport the Partner style connection between the top handle and the trigger handle. It also is the basis of the entire family of saw as all other 8XX and 9XX saws originated from the 910E/EV. As Bill said likely early 80's vintage. Here's my best looking/running example......
Actually yours is not a 910E clutch cover, it's a later 8XX or 9XX cover/brake. Look closely at the location of the two roll pin holes on the two covers....mine are near the top whereas yours are a fair amount lower. The original 910 cover with the brake is very rare.....most 910's were outfitted with later brakes as bands etc were much easier to come by back when they were current. As was said earlier the 910E was a pretty short run for a Jonsereds......when using this saw be very careful if you get it pinched......don't yank on it or you will likely rip the trigger handle AVs out......it was a very weak spot which prompted the development of the 920 and 930 with the Partner designed AV system, which is a much more robust system. However the 910E is the last Jonsereds designed saw. All of the later 8XX and 9XX saws are all of E-lux design.
