Old Stihl chainsaw identification

[Mixinggas]

Im looking for some help i run my 090 for milling and today i was out and saw what looked like a 090 or a 070 with a few missing parts at the end of a drive way with a free sign on it . so i threw it in the back of the truck figuring it would at the vary least be good for parts. upon closer inspection i see that it is different in a few ways with the spark plug hole  being  on its side and  a odd filter set up . having difficulty  telling what it is   serial number is 1126480 . any help would be appreciated thanks in advance

Looks like a Stihl Contra to me

i am seeing that it looks like a lighting wondering if their is a way to tell if its the 106cc or the 138cc one ?

It is indeed a Contra and by the starter cover it's a 106cc. The muffler is from a later 070/090 saw as it has no "catch" for the red "Bonnet" that would have been held in place by the rear catch next to the handle and below the carb. Plus point is the tin cover is there so you have something that could be an interesting project ?
