Picked up this group of Ohio Brass 3-part multi's (M-3156 I think) and a pretty big (huge!) spool from a local classified ad. The multi-part spool is embossed "The Ohio Brass Co. / Mansfield, Ohio". The gentleman I got them from said he found them laying together on a piece of property he recently purchased, between Pueblo and Trinidad, Colorado.

The spool is spoken for, but the 3-parts are all available and can be delivered for pick up at the National show in Farmington. Most are mint.
