um ... er ... well, it's a Hasselblad ... isn't that enough?
Well, no. Not if it ain't working right, producing (unintentional) soft images with light streaks and perhaps variances in interior shutter speed, etc. Afterall, IMHO, it is a work of mechanical and functional art useful to produce other works of art. Not a door stop if it works properly. That's essentially all I'm saying along with I'd keep it and have it CLA'd.
Without guys like John Coltrane, Count Basie and Duke Ellington, life....would be meaningless.
