I've had several of those Hawkeyes, several Kodak Duaflex cameras, a Kodak Six-20 Brownie and a Kodak Jiffy currently residing in storage and they all had the same issue. A shutter feel and response that I would refer to as "mush". I couldn't take a steady handheld shot using these cameras even if I tried. And I was never able to find anything actually wrong with them. Sorry, I know that doesn't sound very encouraging. I tried some powdered graphite to no avail.
