The AK 387 is considered as one of the rarest AK cathedral radios to be found today, following after the model 257, which is the rarest.  The 387 was designed as a farm battery set that was intended to be offered in 1933 but because its late development, it came out in 1934.  It can be found with either Bakelite knobs or wooden knobs and no AC version was made but there was a console version made, the 427Q, which is quite rare in it's own right.
    The 257 is an AC powered, dual band, four knob, export set that incorporates the same cabinet, as did the 387.  From expert and reliable sources, only three 257s are known to exist today worldwide.
    The photo of this set is not historically accurate.  Normally the dial would be white but the dial in this photo is tan in color because this set was originally acquired as an empty cabinet with no chassis or knobs.  An AK 84 chassis and knobs has been temporarily installed until the correct chassis and knobs can be found. 
    I acquired this radio cabinet, at the 1995 I.H.R.S Winter swap meet at the Holiday Inn Southeast, Indianapolis, from a fellow collector.  I spotted him carrying the cabinet through the main entrance door way and before he could set it down at his sales table, I bought it before anyone else could.
