May 1, 20188 yr After the previous thread and seeing the beautiful restoration of a Champion 400, I got the bug to start fiddling with mine a bit again. I had never noticed until I got some of the grime off but they do have a serial number on the top of the casing (flat spot on the removable top to the crankcase in case yours is grimy also). I was wondering if anyone had a way to decode information from the number or if there is some reference out there to help use that to narrow down a production date/decade. Mine reads "No 649509". Would also be curious what other's have just to see what the range is or possibly make a guess that the last 2 digits might be year. Sorry, no way to include a photo as it's hard to see by eye and I had to chase a magnifying glass as it is.
May 1, 20188 yr I'll take a look when I get a chance to get up to my shop. I have two there and one with a freind.
July 1, 20187 yr I was able to take a photo of the serial number on mine.I was able to take a photo of the serial number on mine. ”No 384627 The picture here isn’t great but I think that’s the best when I’m able to take. I tried using chalk to bring out the numbers better, but it looks like they just worked stamped deep enough.
