This is a stock C/G Stagi W-15 LN that was "Turboed" by Bob Tedrow of Homewood Music. He put brass bushings and brass buttons on the stock concertina as the plastic ones were prone to stick. I'm not sure, but I seem to remember reading that he did something to make the action work smoother also. I never played a stock Stagi, so I have nothing to compare it to. I sent it to the Button Box to refurbish the bellows at which time they put leather patches where needed (see pictures and video). Takes 10 full seconds to expand from fully compressed with no buttons pressed.
