I am a bit confused on exactly, or close Simplicity that is the twin, if there is one, of the Allis B110. Also, I picked up several accessories that are all Allis. Are the decks, front blades, sickle bars the same as Simplicity models? I know the sheet metal may be a bit different, but is there a mechanical equal? I will try to get some pics of this package I picked up. It has a fairly nice original B110, dual wheel option, headlights, deck, front blade, Allis wagon, and the jewel, sickle bar mower. I have worked on several Simplicitiys, but not one of the '67-'70 era.
