Thetford Toilet model

Our toilet bowl won’t hold water.  I need to replace the seal.  We are on the road.  Can someone identify the model used in the pre-cassette Thetford so I can purchase the correct seal?  2017 CSS

This is from my set of 2017 manuals.  The Aqua Magic V.

And, a shot from their web page with the actual part numbers.  The Aqua Magic V also has a "foot flush" model, which seems to be the only variation.
