Went hiking and digging along the old abandoned P.C. & St.L R.W. today. Found pole stubs, then lots of Hemi 42 shards as well as some HG CO beehive pieces, then . . . . . My first threadless, laying on top of the ground! Rushed it home to clean and photograph. Turns out to be a CD 731 S. McKee & Co. in blue-aqua with milky whisps and amber swirls in VVVNM condition. WOW!!!! am I excited!!!
