Greg, from everything that I've read Dave played pretty much exclusively stock P-basses during those first 3 albums. I think he may have used flats on the first album and switched to Roto-Sound Swing bass on the next 2 but I believe that he still used the P-bass on all of those albums. I doubt that he would have used one bass in the studio and another live (mainly because those basses play so differently).
But I also agree that there are some pics of him holding a Ric (and Paul Goddard of ARS [who toured some with Kansas] totally adored Kansas and in the later years of ARS he favored a Ric).
I'll have to ask a friend of mine that did a tour with Kansas in 1977-78 if he remembers what pass Hope played then.
I agree that it sounds a lot like a Ric but back in the day we did several Yes tunes and I came really close to the Ric sound with Roto-Sound Swing bass strings on my P-bass.
Well, somebody needs to go interview that dude while he's still around! LOL
I'd love to learn more about his gear. Basses, amps, strings, mics and consoles in the studio, etc. The tone is so incredible. And there seems to be zero info on the interwebs.
