I have a Wilson and Wheeler D-9, serial number 2777196. 5 Drawer cabinet is in gorgeous condition, machine decals are faded, all of the original parts are included, as is the manual (not in good condition, but mostly intact). The gold seal on the base of the machine (near the needle) is perfect. It is fully functional by hand but the leather belt is broken (also included). Cast iron base and treadle are in great condition. I also have the coffin box which is in perfect condition. Absolutely gorgeous!
I am mainly interested in the date of manufacture, or a site I can research more information, but a price estimate would also be nice as I get queries from nearly everyone who sees the machine. I will post pictures as soon as I find my misplaced camera.
