I'm finally completing my collection of this family of saws tomorrow. I found a rear handle S-10 on eBay right here in Cincy and am picking it up tomorrow afternoon. It's a complete saw that looks to be in fairly good condition. The rope won't pull but the guy said he was told the piston isn't seized and it ran just a couple of years ago. Reguardless, it's a complete saw and parts are readily available. The guy I'm getting it from bought it from the original owner who bought it in the 60s. Once I'm done with it, it should look nice setting on the shelf above my desk along with my 07S and 08S. Oh, did I mention I'm only paying $40?
