Here is a tough to find mouse in light aqua:

CD 257 HEMINGRAY // PATENT / JUNE 17 1893 MAY 2 1893 (note error date) -- large SDP -- excellent condition with just 2 tiny flakes on the lower wire groove ridge top and a small open bubble on the back ear top (I'd rate it VNM) -- $110 plus actual postage.

NOTE: I'm selling these insulators on behalf of the Jim Fielding estate -- PayPal (no fee friends and family) or checks are both now accepted - I'll provide instructions. I'll also be handling all the packing and mailing.
