Hello everyone. I just got my first simplex (won't be my last) and I am trying to find out more about it. Based on what I found on this website it looks like it is a pre '48 frame (kickstand is on left rear), has a goose neck style handle bar (as opposed to the plate) and I don't have a number, yet alone a place for the number under the neck. (not boxed). however I have an engine number of "M13376B" , I have a gas tank that seems to match the frame (single fill on right). I have no cover on the right of the engine and I don't know if it was a kick start or push start or what? It does have an extension coming out of the frame under the right side of the engine, but no mechanism on it just a snap ring. I will post pictures of any area if requested. I got it for $600 including clean title. any help would be greatly appreciated. (title says '47 but could be wrong due to human error or year sold?)
