what does 'file' think the file is - i.e. what does
file u1_l0_04-29-09_md1.dump
say?

The dump is compressed. What was the command line you used to create
the dump file?
Have you tried using
restore tzvf u1_l0_04-29-09_md1.dump

I don't think dump has changed anything in 20 years or so! And I
certainly can't see it changing such that it can't read old files -
that is, sort of, it's raison d'etre.
