I have an "Ultra Rare" Dallmeyer of London 17" Telephoto Lens with screw mount. It is made for large format/bellows equipped cameras. Apertures range from a fast F/4.5 thru F/45, big beautiful glass. It is mounted on a small lensboard at present and was used on an Graflex SLR. The glass is spotless, no scratches, mold or fungus and aperture blades move smoothly. The barrel is scratched up in places, but no dents or dings. Also included is an "Rare" Dallmeyer X3 Glass "Green" Filter in superb condition (no scratches). Also included is the original lens hood, front lens cap and leather case. The lens is all metal and very well made and quite heavy as to be expected. Price is 1,000.00 plus shipping for the lot. Please PM me for pictures and or if you are interested. Thanks, Mike.
