Well, I've got one myself and your just the right guy to ask about it. It is a brand new, never had gas or oil in it, Super 2400. Color is dark green, with a nice chrome dual port muffler.
Story is that a customer of mine had this, and I asked him if he ever wanted to get rid of it, to let me know. From what I could find on Mike Acres site, it is around 1970 vintage and 70cc. This saw was intended for export, and it didn't quite make the trip. The guys father was a longshoreman, "and that's how he got it". So, last month the guy brings it into the store, and all he wanted for it, was for me to do a tune up on his snow blower. So, I guess that was the second time that saw was stolen!
I'm not looking to sell it, but how rare is this thing and what would it be worth?
Also, even though I'm curious to hear it run, I will keep it a virgin. I have it on display in the store, and it's quite the conversation piece.
