Ross CdeV No.2?? Your thoughts please.

Hi All,

I just won this old brass Petzval lens. At $135 plus shipping I think I did very well. I'm very good at finding flanges and I have several local sources in my town. I believe from my internet perusing it is a Ross London CdeV No. 2 or something closely similar. The cell diameter is approx 2.25" and overall length 5.25".

My intention is is to use this lens on my 4x5" Sinar Normas cameras. Your thoughts?
