CD 257 Hemingray with the 1890 and 1893 patent dates on the rear. Awesome amber swirled piece. Neat bubbles in the glass as well. Photo taken with flourescent backlighting. I see two open drip tips and two nicked drips. Teeny tiny peck to outside of right ear. The extended ridge, prone to nicks and such, is mint. You won't find one better. Asking $150 and that includes Priority Mail in the US. Outside the US - we'll work it out. Thanks for looking.
