A very long time ago in junior high school I dabbled in the school band. The tuba and the flute were my instruments but I got very familiar and friendly with the neighboring brass and reed sections. Once I finished junior high, I never touched an instrument again and forgot most of what I learned. I was lucky enough to catch these excellent MOCs in person earlier last May during Golden Week (Japan's version of Spring Break) while they were on display at Osaka University. Needless to say but I was hit by a wave of childhood nostalgia. Built by Japanese builder Ryo Arai (AKA -Grie- on Flickr), I was impressed by the attention to detail to all the rods and levers that connect the valves and also how smooth the curves are. Curves aren't an easy thing to pull off with LEGO bricks, especially those that mimic their real life counterparts. Be sure to take a look at all the other angles on his Flickr photostream.
