Has Perrine gone out of business? I Googled "Perrine fly box" toady and the only hits I got was for used boxes at Ebay. When did they stop making their line of spring clips and coil spring fly boxes? Maybe the six that I've had since I was a kid will get valuable. One of mine still has some decals I put on it from a model hot rod I built when I was about 15 or 16.
