You guys seems to be absolutely right. But after checking the net I don't get whether Pons's bass is a Senator or President model. Though that's a problem of the minor scale. Thanks!
While checking for theses basses I also ran across pictures of two Hofners I owned when I was in my late teens: a Violin bass, and a Club bass. Nice basses, though I prefer the Bach T-bird. Played it as late as last night at rehearsal. Wonderful bass!
