    Just back from my holiday and was hoping there was a THOR serial number expert surfacing over the holidays.

    Maybe you have already seen this, but here is a closeup of the engine from that blog post.

    Interesting Martin. Thanks for posting. I noticed that the engine had a schebler carb and not the Thor carb. The mystery still to me is when a letter is used on some serial numbers and why? Also like on my engine some have a number followed by a dot and then presumeably the 4 digit production number. HHHMMMMM

    Hello,
    I'm not sure if this will help, or make things worse.....but I have an original 1913 Thor sales brochure, and it has a picture of the single motor, and the S/N on it is U 4 with no dot or punch mark between them.

    Thanks for the re-size Martin! It shows my eyes were off and it definitely is not an 8!

    At this point not much can make it worse Runnlo.... the brochure you are referring to should show a different cylinder than Ross' engine.

    I'm still hunting Ross and asking folks that may know. I just thought of another fella that may have info and will follow up this evening. The THOR experts are rather scarce in these parts it seems....

    I noticed that the cool Thor engine with the schebler carb did not sell yesterday at the Bonham's Vegas auction.

    http://www.bonhams.com/auctions/2046...3D21%26r1%3D10 I think they took a stab in the dark putting a date on it. C. (circa) is a pretty handy term I think.
