Ok, separate subject here. Your Bass looks to have the German type hatpegs. Two of the Bassists in the Philly Orchestra (Robinson and Rosengard) have hatpegs on their Italian Basses with Chromatic Extensions by I think Robertson's which are very similar to the ones I have by Arnold. BUT, their Basses have the Italian style Hatpegs which do not stick out as much as the German ones. I have the Italian ones on one of my Italian Basses now in restoration. Look at the pics below to compare.
I have seen many German hatpeg 'be-headed' to size down to the Italian style ones. You can cut the
'hat' portion off at about 1/4" after the metal housing and slightly round the edges and then paint it black with a marker. No one will call you
the executioner..
