Hello!
Cleaning the closet for odd LF stuff to help ebay along (....), a large Schneider centre filter aquired in a trade-deal is on it's way off. But I have a problem of with this one, as I do not know which lens it would work properly on. It comes in a fitted, brown leather case, have black (heavy) mount of nothing less than 110mm outer diametre and will fit on lenses with 82mm filter threads. There is no manual/directions with it, and the only indication is that it's written "Center - filter IV" on the outer side of mount, and a paper-sticker on the leather case also stating "IV". I would be happy if any of You could tell me which lens (es) it will work on so I am able to ad. it properly.

Thanks!
