<p>I have a 1950s-vintage Linhof Super Techinka 2x3 (s/n 44200). A user's manual, presumably of the same vintage, states that to correct for longer lenses the eyepiece pulls out a bit. I am unable to pull mine out without more force than I am willing to use for fear of damage. My question is whether the eyepiece is just stuck or whether the eyepiece on some versions of the camera did not pull out. Any LInhof mavens out there?</p>
