An excellent vintage Bausch & Lomb Unicum Shutter with lens for large format cameras. We believe this is the 8 x 10 film size. It is marked "Bausch & Lomb Opt Co Pat Jan 6 91" under the barrel of the lens. This is the large scale aperture which goes from 256 to 8 (and even slightly lower). We can't say if the timer is accurate but the shutter does fire on all speeds. It might stick on the "T" setting, we aren'...t sure if that is normal. The pneumatic system may need a tune up to adjust the accuracy. The lens is unmarked but appears to be the original one it came with. Based on when it was made, we believe it is likely a ground glass Zeiss lens. The glass appears to be in excellent condition. The glass could use a cleaning by someone who knows what they're doing. There are no deep scratches or scuffs. If there are any light surface or cleaning marks, they are light enough to be invisible to us. There is a small amount of what looks like dust. We were able to remove a few specs of dust with compressed air. Cosmetically, the body and mechanisms look fairly clean with some normal minor signs of age or use. There are a few scratches around the edge of the barrel in front as shown. They extend to the exterior edge of the lens but not into the interior or glass. The shutter comes with its original mounting ring which is attatched to the face of an old camera. You could certainly salvage the mounting ring so that this shutter could be used on a new camera. The total diameter of the shutter is 3-1/2" or 10 cm. The lens measures 2-7/8" or 5 cm in diameter. The interior diameter of the glass is 4cm. The Length from glass to glass is 7 cm. The wood piece is 3-3/4" x 3-3/4". Please refer to the photos and ask any questions prior to bidding. We are happy to provide more photos or measurements. A very nice antique mechanism from one of America's oldest optical companies. A perfect addition to any collection. More pictures available upon request.
