Yeah, the two top handled saws are Stihl 08S's.
Made in the 60's , they are good old saws, they cut alot slower that modern saws, but are very solid, all metal no plastic. They have got us out of the [bad word] a few times!
The one with the 20" rail was my granfathers, its been in our family for over 30 years and has cut some serious timber!
The one running the 25" was given to me this year by a friend, its very gutsy and runs a .404 25" easily. It feels very well balanced actually.
Made before chain brakes though !
