I sold this one a while back, and finally got a photo of it to share. It's a CD 126.4 embossed on the front crown: W.E. MFG. CO. Embossed on the front skirt: PATENT/ DEC. 19. 1871 Embossed on the rear Crown: W.U. Embossed on the rear skirt: A This should be EIN [040]. It is in a pale green aqua color, but the feature is that wild big bubble on the side. It is open into the threads. Very cool looking piece! Formerly in the collection of Bob and Phoebe Adams of Miami, FL
