Lynn,  Most Regina disc boxes have a serial number stamped on a small
raised area on the bedplate or, in some of the earlier boxes, into the
circular platform on the center spindle.  Since your chime clock would
not be one of the earlier Reginas, look near the center spindle.

Once you have the serial number you can get from the Musical Box
Society International, which is the keeper of the old Regina factory
records, the pedigree (copy of the original Regina factory shipping
record) for your particular Regina, showing the date it was shipped
and to whom.  You will need to send a check for $2 made out to the
M.B.S.I., to Bob Yates, 901 Glenshaw Avenue, Glenshaw, PA 15116.

Regina was one of the big three disc music box makers in the world,
before radio and the phonograph ruined the market.  The other two
companies were both German (Leipzig) firms, Polyphon Musikwerke G.m.b.H
and Symphonion Musikwerke G.m.b.H.    (G.m.b.H. stands for Gesellschaft
mit beschraenkter Haftung, the German equivalent of "Incorporated".)
After the music box market collapsed, Regina turned to making vacuum
cleaners, which it did until at least World War 2.

Q. David Bowers' "Encyclopedia Of Automatic Musical Instruments"
devotes pages 170-212 to a richly illustrated history of the Regina
Music Box Company, Rahway, N.J.  On p. 210 Bowers explains that Regina
made two type of clocks.  The standard type used regular Regina
plucked-comb musical movements of the 11" or the 15-1/2" disc size,
usually with duplex musical combs.  But the second type, the Regina
Chime Clock, was not actually a music box.  It was equipped with a
series of tuned chimes or bells, which were actuated by a disc.

To quote Bowers: "The musical mechanism consists of tuned bells, each
with a resonator (tube) which gives the sound a 'depth.'  The bell
strikers are operated from two actions which superficially resemble
musical combs.  Some bells have multiple strikers so that a given note
can be repeated quickly (without having to wait for the striker to
re-position itself).  The music, two series of chimes and four musical
tunes, is programmed on an easily-changeable 12 1/8" steel disc."

Bowers then lists eight models of Chime Clocks (illustrating only the
style 81):

  Style 80 (serial nos. 8000001-8100081 (1905-1906))
  Style 81 (serial nos. 8100001-8100081 (1905-1917))
  Style 82 (serial nos. 8200001-8200013 (1906-1908))
  Style 83 (serial nos. 8300001-8300018 (1907-1912))
  Style 84 (serial nos. 8400001-8400012 (1906-1908))
  Style 85 (serial nos. 8500001-8500020 (1906-1909))
  Style 86 (serial nos. 8600001-8600011 (1906-1908))
  Style 87 (serial nos. 8700001-8700022 (1906-1912))
