If you read my post again, I think you might recognize that my suggestion was primarily to use Seth himself as the resource and that the listed catalogs might offer some information that could potentially be helpful. My experience with Seth has been that his expertise far eclipses the info in the catalogs. Having said that, yes, I have done this kind of research on his site for many items in which I have had personal interest, including four Wollensak lenses. Sometimes I have found exactly what I needed. Other times not, but all have lead me to further avenues of research and great interest in what I was exploring....thus the suggestion to check those out.
Have a nice day.
