What you are showing is a bellows and a focusing rail For a 35 mm single lens reflex camera. Units like this were popular in the 1970s and 1980s for high magnification photography. The camera lens or an enlarger lens is mounted on the front of the bellows, and the focusing rail allows you to use various degrees of extension. Think of it as it continuously adjustable set of extension tubes! Oftentimes these were used to make duplicate 35mm slides, and Nikon used to call these by various model numbers beginning with the prefix PB
It's a bellows used for macro (extreme close focus) photography. A lens fits on the mount end shown open in the photo and the camera attaches to the end shown capped in the photo. I'd date it from the latter 1/4 of the 20th century -- probably sold for use with a 35mm film SLR. Joe
Thanks guys. Was going through some estate boxes and found this. Wasn’t sure if there was any value here so I figured I’d consult some experts.
It also depends on the mount. Minolta and Canon are quite common along with Pentax. Others are a bit rarer and have slightly higher value IF the bellows are in good shape.
The rear cap has grooves...looks like a Nikon F mount cap...is there a brand name? Spiratone sold a lot of rather inexpensive units back in the day.
look on the bottom of the rail for identifying marks or a sticker. Your photo is of the front mount. " leitz Wetzlar "---makers of the Leica camera!!!
