GNUPG uses Blowfish in standard CFB mode (without the PGP 2 byte
feedback) and a 160 bit key.  A 128 bit version is also available
and this still uses standard mode - if there is any other OpenPGP app
which uses Blowfish, I maybe able to switch to PGP CFB mode for this
128 bit key version.

By the way, how can I get an assigned number for my (standard) Blowfish
