Hi Diana,
I added schmatic pics of 8, 9, D9, & 12 to Photos in "W&W Parts Schematics".? Once downloaded the pics can be magnified.? The schematic are from a? Excelsior Supply Company catalog c.1910
I found the descriptions of W&W 9 and D9 interesting.? The D9 is described as "Wheeler & Wilson No 9, Latest (Formerly D9)" .The #9 is described as "9-1 machine formerly old style 9".??
Jon? ?
