Here was I was able to find about the current hash and cipher choices with gpg
Pref Code (n) Algorithm (name) PGP 2 PGP 5 PGP 6 PGP 7
PGP 6.5.8ckt GPG 1.0.6
s1 * IDEA X X X X X X *
s2 3DES --- X X X X X
s3 CAST5 --- X X X X X
s4 Blowfish --- --- --- -- X (03) X
s7 AES (128) --- --- --- X (7.0.1) X (03) X
s8 AES192 --- --- --- X (7.0.1) X (03) X
s9 AES256 --- --- --- X (7.0.1) X (03) X
s10 Twofish --- --- --- X X (03) X
s11 Camellia128
s12 Camellia256
* only with IDEA module

Just a few questions,
#1 - How can I generate this list with newer versions of gpg -- is
their an internal command that cross-references the s or h numbers
with the specific ciphers/hashes that are compiled into the module --
something I can type at the command line?
#2 Historically, what ciphers were eliminated -- For example what
ciphers were in the s5, s6 slots? Same with the hashes. I believe
the TIGER has was equal to s5. What happened to that hash choice?
Thanks for your help
