The format for the PDS you supplied is known, it's iebcopy unload format.

How much it's mangled isn't clear, it would take looking at more of the
file (and/or other files) to see.  It's likely all the PDS source FB
files could be recovered as they are unlikely to have binary data which
would typically get mangled in them.

It's certainly possible that any binary data isn't recoverable like load
module libraries or raw binary data.

Even FB source data can have a surprise or two.  I've seen a "not" sign
get translated on download into a UTF-8 "not" sign -- this made the 80
byte record longer than 80...
