Here's a vintage camera mystery for the RF Forum hivemind: What's the story behind this apparently one-of-a-kind half-frame Pentax KX? I snared this unicorn at the Pasadena Camera Show this past weekend; the seller got it from an estate sale on rubylane.com. It's got a modified film gate, masked-off viewfinder, a regeared film advance, and a handwritten 72-frame insert for the frame counter. Beneath the gate is inscribed MODIFIED BY KLINGER
, and other inscriptions read I.M.C.
and TITLE IV B
. Tell me what you know!
