A photographic lens labeled: Wollensack Optical Company, Rochester, N.Y., USA, STUDIO #3, VERITO 11-1/2" DIFFUSED FOCUS F - 4, The number 7269 is stamped/engraved into the silver ring which adjusts the f stops which range from 4 to 45. The shutter has an "OPEN - CLOSED" finger switch control with no timing mechanism. There is an attachment point for a remote shutter control cable. The inner lens has etched into its rim the number 37341.There are 4 sets of extremely fine threads which allow for the disassembly of the lens: one to remove the inner lens, one to remove the outer lens, one to remove the shutter assembly, and one to remove the entire "barrel" of the outer lens. This outer lens has a slot to allow the insertion of a filter, I think. This entire lens assembly is attached to a camera board which is imprinted with, I would guess, the camera manufacturer's name: BURKE & JAMES, INC., Chicago, Ill., USA. This board measures 6" x 6". The lens is approx. 4-1/4" long by 3-1/2" diameter. The shutter compartment, located in the center portion of the lens barrel, is approx. 4-3/4" diameter including the silver adjusting ring. There is a patent label which reads: Patent Mar. 12, 1907.
