Does anyone own Fidelity 11x14 film holders ? I've just bought 4 holders from ADORAMA and found the fact that the flap area do esn't set properly. The cloth-bonding part seems fatter than it should be. The a rea collapse a liitle bit When I pinch. The holder is engraved "MEDICAL HOLDER". Is this for usual film holder for 11x14 sheet films ? Anyway it doesn't look like any other Fidelity holders I'm using. Please give me advise.
