FS: One beautiful brass lens. This is a Hyatt Rapid Atelier /5 lens. Widely acknowledged as a re-branded Wollensak Vesta, this is a Petzval design. Lens is marked for the whole plate format 6 1/2 x 8 1/2; focus is about 12 inches. Glass is clear with a very slight bit of separation at the very extreme edge under the words "Rapid Atelier". It does not affect the image. Otherwise no issues. Flange is included. Pneumatically-operated Studio shutter has just been cleaned and adjusted and is working very nicely. No bulb included. $525 plus shipping/insurance/PayPal. No trades. Domestic shipping via USPS Priority Mail. I'm happy to ship overseas via USPS Express Mail International. But please do not ask me to falsify customs forms.
