I know I might seem a bit a bit thick ... but whats an AV ?? 

Anti Vibration mountings that isolate the engine and bar from the front and rear handles . Hand Arm Vibration Syndrome is a degenerative disorder of the nerves and blood supply, it is incurable so best avoided, we used to know it as "white finger" and I developed it many years ago

I don't think so but then neither did most saws of the period. The first forestry saws I used around 1975, Jonsered 621/80, did have AV but no chain brake, first saw I had with a chain brake was probably Husky 162.

Yea . The two saws I had Were a little Alco top handle with no AV and a big old Jonsered 621 or 601 they look similar . All metal ! Justb remembered ...contact breaker points ! 😀  @openspaceman

Yep when you pick up a 621 now it feels amazingly heavy but it was so much lighter and ergonomic than the Danarm 110 I had used on the fsrm before. The first chainsaw I bought as a self employed feller was a HUSKY 280 cd  the cd meant capacitor discharge I think. I wanted a Jonsereds because they were "cooler" in the forest but a discount shop in the hills above Haslemere had already sold me a husky 165r a couple of years earlier so I went with him.

When I look at my granddad's Dolmar 112 it was pretty advanced for the time which must have been end of 70s. AV, chain brake, wide rear handle guard, some plastic covers to save weight.
