I've definitely seen 1/2" acetate tape, not 1" though. However, was 1" used in instrumentation 
purposes in the early and mid 50's? If not, someone made tape for Les Paul and Atlantic Records, the 
first two 1" 8-track machines.

I came across a fair bit of 1/2" acetate in the Living Stereo
remastering project, but it all disappeared around 1958 or so. After
that it was all Mylar except for the odd roll of 1/4".

All the best,
