Can you  provide a hex dump of the first 128 or so bytes of the archive?

I have a very old cpio archive written in approximately 1990.
It was most likely written on a VAX VMS (~linux) system.
This is historical data and fairly important...

When I attempt to get the files using:
cpio -iv --no-absolute-filenames --force-local --format='bin' < FILE_001 

I get the following output:
cpio: ecl9w2: unknown file type
ecl9w2
cpio: g: unknown file type
g
cpio: ssss: unknown file type
ssss
cpio: t: unknown file type
t
wwww
5480 blocks

When I then do an 'ls', the 'wwww' file has been created.   But none of the other files:
'ecl9w2', 'g', 't'
exist.   
The 'wwww' file is ascii and readable.   I know the 'ecl9w2' file is binary.

Any suggestions?
Thank you,
Alice
