That was created by an very old PGP-2 versions.  gpg bever created a
version 2 key.

The formats are diffefrent and even if you would use the same key
material, the fingerprint and the keyid will be diffewrent.  Thus there
is no practial way of using it [1].

[1] if you use the key material and make a v4 key out of it, gpg should
    be able to decrypt keys with a wild-card keyid (--throw-keyid in
    gpg, can't remember the PGP-2 option).
