I didn't seem. Often I had to infer which system a tape came from from
its contents. Some tapes have photos of the label.

I have seen many variants in there, such as little or big endian record
size, records padded to 16 bits or not. Some records have frames
dropped from the beginning or the end.
Also old ITS backup tapes were transferred from low density tapes to a
fewer number of high density tapes in the 80s, so sometimes same file
appear in multiple savesets on a single tape.
