The Historical Arts Casting folks don't have our original pattern tiller head (they have the 1.5" straight and the 1.25" bent arm from the later Bill Shaw Pearson 26).
Thinking i'd start with something that at least looked like our original pattern (and being told it could be bored for 1" ) I ordered the 1.5" pattern.
Bunch of nice folks, the casting quality is very nice. one little problem, the casting they sent was cast with an 1.25" hole. Thought about fitting a sleeve or sending it back to get re-cast, I haven’t decided yet..
