What key is the harmonica on Blonde On Blonde?

Which key is the harmonica that Bob Dylan plays on his Blonde on Blonde album, specifically ABSOLUTELY SWEET MARIE, I WANT YOU, JUST LIKE A WOMAN, and PLEDGING MY TIME?

from what I can find - all of his songs (and I may be wrong) were played on either a C or a B (not Bb) harmonica. At least those are the only 2 keys his signature harmonicas can be purchased in so I’m guessing those are what he played. And am guessing, sorry I don’t know for sure, that most if not all of those songs mentioned were played in key of C. Hopefully someone with more knowledge than me can chime in. I just hated seeing this message hanging out with no answers.
