Thanks everyone for preserving these items.
In the unpacked file dectapes-extracted.zip, folder 118655.tu56 has
within it BASIC.P11.txt, the filename suggesting it might be a version
of BASIC, but the header of the file is this:
;FOCAL-11, VERSION B2
;BY RICK MERRILL
;COPYRIGHT@ 1970,1971 BY
;DIGITAL EQUIPMENT CORP, MAYNARD, MASS.
overall the file contents suggest it is FOCAL, is there a way to check
that this is what was on the original tape? and not a handling problem
during the recovery?
I dumped the tapes and can confirm that this is not an error during
recovery and is what was on the original tape; each tape had a printed
directory listing taped to it and this listing matches the listing I got
when extracting the data. I assume it was misnamed or overwritten at
some point back in the day.
There is a BASIC.P11 on another tape that has actual BASIC source in it.
There's also what looks like some very early RSTS source in there.

As an aside there is an early version of TECO-11 there too:
