Hey Rick

It's a Series 4 Eurynar and double Gauss in design.

This catalog has correct information for your lens so look for the Series 4 as they made them in different Series varying only by lens speed.
Here's a link to Camera Eccentric thanks to Seth. http://www.cameraeccentric.com/html/...enstock_2.html

The use of 'Double' back in the day did not indicate design necessarily but more that the lens is convertible in the way of two different focal lengths or a symmetrical design like yours. The quality when converted was not always so good pre-coating w/ 4 air to glass surfaces but could still make a fine portrait lens converted.

Thank you so much, Louis (and Seth). The link was very helpful. I've not been a member of the forum very long, and his was the first question I posted. I will do my best to keep my questions relevant.

Since you're new, I'll clue you in that if you click on a user name, go to profile, down the left there's a mechanism to add that user to your ignore list so you never have to read them again.
