There were a couple of designs for the Schneider and Rodenstock 135 lenses. I remember that one of the designs was older and did not cover as the more modern design. I have the most modern 135 Componon-S, and it cover the 4x5 neg just fine. ( It is used on a Saunders 4500 enlarger.).

Maybe you should post what the 135 looks like, and maybe someone can tell you if it is an oldie... like a chorme lens rather than the more modern all black lenses....
