Scotch 777 "blue label" tape blues confirmed

[Chuck Guzis]

This is in reference to my earlier post about Scotch 777 half-inch
open-reel tapes.  I'd reported that I encountered a tape that displayed
binder bleed, such that the tape would stick to the heads and guides.

This was a tape that had been both baked and cleaned.

Coating the tape with a film of cyclomethicone allowed it to be
successfully read.

In the latest batch of tapes, I found another one--it behaves identically.

These appear to be only the blue foil-labeled 777s; the yellow paper
labeled ones are fine.

I estimate the manufacture date to be about 1969-70.

FWIW,
Chuck
