Looks like one of those Bach/Bundy/Selmer souzys... But you're right about the bore. Should be .736" or so. The King/Reynolds/Olds sousas are about .688". Don't think this one's an Olds or King as the seller suggests.

Well... just to make sure... I just trotted the 2nd slide off of my Bundy/Selmer commode-O-phone down to the shop and it measures about .735".
