Anyone know about this lensThornward symmetrical convertble series IV f8 6 1/2-8 1/2 ??? : LUSENET : Large format photography : One Thread

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 & James 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 Chicago, but I have never heard of this lens and was curious if anyone on the forum has had experience with this lens, is familiar with it it's performance or can provide any info on the Thornward Co. Thanks
