Beautiful lookin' little unit here ! -- CD 188 Patent-Other in a stand-out glowing green ! The Nov. 23d 1886 date is weak as many of these are. Has a fold in the glass on the backside top starting into the pinhole that I'm sure was there when it left the factory. It's not damage. Usually 187s/188s have chipping around the edge of the pinhole but this one has none. Easily VNM and oh that color !! $75.00 + shipping. First email that says' "I'll take it.". No PayPal. Email with questions.
