Identifying hash type

Hello there.

I'm actually stumbled as to what those 22 character hashes are.

Obfuscated as per the forum rules. Don't seem to be base64. Obtained during a pentest of a custom CRM developed ca. 2002.

hash-identifier (https://code.google.com/p/hash-identifier/) doesn't seem of much help.

Any ideas?

Thanks.
