The location of this theremin is unknown, but should be in the Caramoor Center for Music and the Arts
Five octave range with slightly higher upper register (implication being that more of the extended range was at the low end), tone color switch (not reported but a given, in that Lev had already added this to her RCA theremin, giving it two tone settings. The January Theremin probably had more tone switch positions).
This theremin would have been state of the art at the time it was made, and very comparable to the 1938 Rockmore Theremin. The January Theremin may also be the first theremin with a pitch indicator (in this case, a neon lamp).
