In a box of old camera stuff left to me by a friend, I found a Waterbury lens, Scoville Manufacturing Co. NY. serial #4467. No slot for stops. There was no glass in the thing, but the box also contained a single cell and the small threaded ring that held it in the rear of the lens. Here's the question: As far as I have been able to find, the Waterbury lenses are listed as having a cemented doublet for glass, not a single lens. Was I incorrect in assuming the lens belonged in the plated barrel since it fit and was in the same box? I mounted the thing and shot some 4x5 TriX with it the other day and was amazed at how sharp it was! I was comparing it to some old Rapid Rectilinears and a mystery lens from Wollensak in a low end shutter, mind you, but it looked pretty good. I plan on trying some portraits with it. Can anyone point me to a good source of info on these lenses? My thanks in advance to the kind and knowledgable sages who haunt these threads and provide information to ignorant and enthusiastic idiots like me who love to play with this stuff. You shouldn't encourage me, but you do!
