Not on Sam, but with Barlow Pass, I'm running 43mm Honjo NM29-700N from Jitensha, and they're a perfect match. What I like about Jitensha is they sell un-drilled fender blanks, so you put all the holes right where you need them.
Mine are fluted, but the sell the same size hammered, HI27-700CN
They also sell all their hardware separately, so you can get just the mounting stuff you want. - They are not inexpensive....
I think you can fit wider fenders and tires on a Sam.
