Hello everyone, First of all, I want to thank everyone on this Forum for making it such a valuable resource. Now for a question, I just purchased a Burke & Jame s 5x7 Commercial View camera and included was a Thornward symmetrical convertble series IV f8 6 1/2 - 8 1/2 lens. This lens was originally manufactured in Chica go, but I have never heard of this lens and was curious if anyone on the forum h as had experience with this lens, is familiar with it it's performance or can pr ovide any info on the Thornward Co. Thanks
