Hello all I have been reading the forum for awhile and I finally registered.  I restore old Stihl chainsaws but don't recognize this one.  Can anyone help and tell me what I should offer on it.

that thing is 1950's/1960's
buddy has one very similar to it, his is direct drive too.  my buddys saw is heavier than heavy! 

lumberjack48  was talking about something along this line of a saw in a past post.

O51AV  ???

Air cleaner looks non-standard though

Think you will find it's a 70's vintage.

Yeah I was thinking 70s vintage as well.  The two holddowns on that weird air filter cover are  what are throwing me off.

The air cleaner looks like the type that Stihl used on their concrete/chop saw models.

I'm not so sure it's not maybe a power head off a TS 510 chop saw. You are right about the air filter cover being one from a chop saw. I know of no Stihl chainsaws that used this type of cover

You guys nailed it.  I checked it out and it is in fact a TS510 chopsaw.
