So I went back and looked at the 120sia at the pawn shop yesterday, Friday. It has the metal plate saying it is a 120si, made in Germany. That should make it after the reunification, right? But it appears to have a repair, some kind of body filler maybe, covered over with an epoxy or something, The epoxy was peeling a little. It was on the right hand side of the saw, just ahead of where the handle comes in. Looked to me like it would be in the gas tank. So I figured I don't really need another saw in that size range if it is going to have a leaky gas tank. I more nearly need a smaller (lighter) saw for limbing and carrying around in the woods cleaning up smaller down stuff. Another pawn shop has a Poulan Super 25DA Automatic, but it sure liked like it said Super 250A Automatic.
Thanks for all the help and advice guys.
