The most distinctive feature of the 2100 is the shape of the key cups. The concept was very modern and futuristic, so they are quite distinctive. We've shared photos below to compare the 2100 with its successor, the silver Handmade Conservatory. As far as the mechanism, they only other major mechanical difference between the two is that on the 2100, the feet of the key tails hit tabs on the ribs -- whereas the key tails on the Handmade Conservatory touch the body. In general, the key arms, especially at the points where they wrap around the mechanism tubing, are "flatter" on the 2100 when compared with a more traditional, "double beveled" shape on the Handmade Conservatory. Our repair technician, Rachel, said, "The 2100s may look a bit funny, but they play so well." So, if you happen to see a very distinctive looking Powell with very different key cups and more angular stylistic elements, chances are it is the 2100!
