This is a "new" guide to replace the "old" guide at the PGPOG. While the "old" guide covers most Sheridan guns there are a few holes and it only includes pump guns. This guide covers all Sheridan guns to the best of my knowledge and includes some additional information as well.

Many thanks to Painthappy, B, Bored383, and Drum for some of the below pics. Need to identify a Tippmann? Check out Kampfer's Tippmann Recognition Guide.
