This may have been discussed before on MMD.  In "My Isle of Golden
Dreams" (not one of my favorites) there is an unusual perforation in
the extreme treble.  It's on a cheap 49-cent 88-note roll of unknown
manufacture.

The perf occurs every 3.25" and is about 1/8" long.  I wonder if anyone
else has encountered this oddity?
