Is this tar file from an email or something? Is it MIME::Base64 encoded, or encoded by another method, or is it binary?

PGP/GPG signed files should not modify the information between the 

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

[download]
and 
-----BEGIN PGP SIGNATURE-----

[download]

tags, the only thing I've noticed is a munging of the .signature delimiter -- to - --.

Sorry if I'm stating the obvious with this, but one thing that's just struck me, crazy though it is: you're not trying to get a file from something like 

-----BEGIN PGP SIGNATURE-----
Version: GnuPG v1.0.6 (GNU/Linux)

iD8dBQE8Rg1UOcb+EPeM7ggRApQSAJ0dqFfLKZ5QkRUAHJFZHcjJ5dV2-QCeOPEH
ybtpRe\\KLR7bCdt0YOtcnk=
=dugR
-----END PGP SIGNATURE-----

[download]

Are you?

That's only a signature which is sometimes distributed as another file - for example the linux kernel tarball has a kernel-2.x.x.tar.gz.sign file associated with it, which contains the PGP signature for the kernel tarball.

You use that file with PGP/GPG to check that the (in this example) kernel tarball hasn't been changed - similar to checking an md5sum - the tarball isn't part of that GPG signature!
All the signature tells you is which key/who signed it, and gives some checksum information for the file you should check it against.
