having just aquired a pre war K (1935), with all intentions of selling ! i mistakenly joined this forum and suddenly back stepped the idea and began to read and ask questions ! as one poster commented , the recent purchase is why the confusion of its popularity ! just by sensing the " pure enthusiasm" from k owners on here haulted my rush to sell , and ignited my rush to learn ! they do have a magnetic charm that lies just beneath their vintage patina ! what that charm is , i dont know ! but i am closer to finding out thanks to the informative members of this site, whom find no hesitation displaying what they feel when a uneducated newbie stumbles into their mist !
