I can't claim to be an expert either Gadge, but i do love the mobilco / echo saws, which as you say were beautifully built, and if my 452 is anything to go by, will never die!! Dad worked for Mobilco till it was sold off, then Ariens Echo till he retired. I worked with him on and off for many years and collected stuff as i went, Most saws i have are really good examples with my favorite being the 60s. sounds like you where pretty close to them as well. I've been rebuilding Dads model 5 since i pulled it apart as a teenager, a mate resprayed it and most of the parts are off the original machine, i do have the wire recoil starter, but it needs to be painted and i haven't been game to pull it apart!! As for the 50th, i got that as a trade on a victa ute and your right Jack , probably will never use it, how to preserve it is always the question ah.....i'll take a picture of the underside for you deisel. cheers pete
