Early Buffet R13 clarinet comparison—1963, 1962, 1961, 1959, 1957 German Silver Keywork

These are all real Buffet R13's...but the solid German silver keywork, and differences in thickness of walls and tone hole placements creates horns of various levels of "vintage" feel and sound. Personally I love the tone on all of these, but I wouldn't necessarily play all of them in every gig with the same enthusiasm. Which is your favorite?
