Don't know if you'd call this an ad but guess it is as it is a wall poster for a Saw shop. It is pretty detailed and would help out a saw mechanic. I got it off eBay a few weeks ago.
That's our dinning room 5' table. The poster is actually 44" x 33". It's got incredible detail and 'insight' into the Contra/Lightning. I'm guessing this came from Canada as the saw was called a Lightning in Canada and Contra in the US.
I know its an old thread and some of the uploads dont work any more.
But do you still have some adverts or other stuff of the Stihl history and the big saws like Contra/lightning and 070/090??
Would love to se what you got on these old saws.
