Chord request: Diminished Major 7th

[pdxdjazz]

Wouldn't the bass notes be different i.e., C to Eb. In one chord it would be C - C sharp (Db) - Eb. In the other, C - D natural - Eb.

I think in the player, a bass note designated by a slash is pedaled. (In this case C) the "walking scale" would be up to the reader. So you agree that just from a notes-in-chord perspective the two chords contain the same notes?

Cdim maj7 = C Eb Gb B
What notes are in B/C ?
