Greetings Ladies and Gentlemen, I have an old brass lens with the following info on it
Harrington $ co Sydney Brisbane etc
Series D Rapid Euryscope
Its either made in Australia or imported and rebadged. It has a iris range frn f9 -64 and I have no idea of the focal length as its not mentioned
Any further info would be greatly appreciated
P.s. while I'm at it I thought I'd post a pic of my 7inch Verito(all the wollensak lit only mentions 7 1/4 inch lens. Is this a custom length?
peace and goodwill fergs
