Bought one at a sale in Okla today for $400. Couldnt read the SN so as to date it. Tin is great other than a dummy cut out a piece and installed an altinator. It dosent have the hand crank, or the belt pulley attachment. Has one bad front and back tire, but I have those here at home. Wheels are GOOD It has the air cleaner without the glass jar. Does that date it? I have a 1941 M that my dad bought from my uncles sale in 1965 for $500. It has the cleaner jar. I cant imagine somebody putting that on if it didnt come out with it, but you never know. Dad had a 48 H back in the mid 50s, but I dont remember what it had
