The Wurlitzer 112 is an electric piano that was made in the 1950s.  I believe that it was the third electric piano made by Wurlitzer, with the 110 and the 111 being the first two.  There aren't too many features on the 112, as it simply has a volume knob.  It has a sustain pedal, although the one that I have used didn't have it, so I can't say how the feel of it is.  It also originally came with legs, but over the years many of them have lost the legs.  These are quite rare in general and are pretty hard to find information in detail about this old instrument.  I can say that the action is pretty good on this as it is an easy instrument to play.  The tone is definitely that of a classic Wurly electric piano as you would expect, although the degree that you can alter the sound is minimal as this model doesn't have any parameters beyond volume to work with.  It also doesn't have any built in vibrato, but use the vibrato on my '76 Fender Twin Reverb and it sounds awesome.  The tone is definitely comparable to any of the great sounding Wurlitzer electric pianos out there that I have used, but probably wouldn't be my first choice as because of the limited parameters that it has to offer.  Nonetheless, this is a great sounding keyboard and is a great collectible as well since they are so rare and hard to find.  I have seen the price of these range from pretty cheap to quite expensive and since they are so few and far between, it is hard to gauge an average price on what one of these in good shape is worth.  All in all, if you stumble upon a Wurlitzer 112 I would definitely recommend checking it out, but if you are looking for a more reliable Wurlitzer electric piano with more features, I would look at the 200A.
