Early Barbet stud

Marquis 1934

So why wasn't this stud ever used? or maybe he was and there are no records for him.
I like him, but that is because at the moment I am working Bepop more as a land dog than a waterdog so I am attracted to dogs that look like they can do a days work on the land (with no grooming!).
Marquis would struggle swimming all day, he is a classic barbet griffon, a time in our barbet history of transition.
