Olds Super Recording Models
When Olds introduced the Super Recording Model trumpet and
cornet in the late 1930s, they had been making trumpets for
about ten years and trombones for at least ten years before
that.  They had introduced the Super Olds trumpet (from
which the Recording was derived) a few years prior to this and
it had become quite popular.  Olds had been experimenting
with new bell designs and it is possible that the earliest
Recording models utilized one of the early Super trumpet bells,
but in later production they were distinct.  The bell tail was
longer, which placed the valve section more forward.  This was
somewhat like the Selmer Balanced model that Louis
Armstrong had started using exclusively in 1933.  In addition,
the second valve was offset to the left, putting it more easily
under the second finger.  Olds had made trumpets with the
offset second valve previously, but now it was part of a
specific model design.  One of these earlier trumpets is #2931
made about 1936 according to factory records, is in the fifth
photo down to the left.  I sold this trumpet to collector Arnie
Ruskin and it is now in the National Music Museum.  The
Super Recording trumpet was actually designed for use in the
recording studio and specifically for Harold Mitchell, who at
the time, was the most sought after for this work.  Harold
Mitchell's son, Ollie, still owned that first Olds Recording
trumpet at the time of his death.  Ollie had his own very
successful career as a studio trumpet player.  I have not been
able to determine the date that the first Super Recording
trumpets and cornets were made, but they are not yet offered
in the 1939 Olds catalog and I believe that it was at about that
time and may have been available in small numbers before that
date.  Hopefully, more data will come to light in the future.  
The sixth photo down on the left is Harold Mitchell's first
Recording trumpet, serial number 6085 and the next photo
down is number 6086.  This now belongs to Southern
California architect and designer, David Rich, who purchased it
from Harold Mitchell in about 1942, when Ollie Mitchell was
serving in the military in Europe.  David was in high school and
taking trumpet lessons from Mitchell.  Notice that both
trumpets have the same, odd, mouthpiece receiver.  David told
me that it was installed on his by Dominic Calicchio very early
on, to reinforce the receiver.  I have not experience any
weakness in the receivers of Olds trumpets from these years,
making it a surprising addition.  These two trumpets are both
the large (.462") bore that was only offered in
Super trumpets
in the earliest production.

The Super Recording trumpet shown in the first four photos
was made about 1947 and retains the original case,
mouthpiece, lyre, warranty and inspection cards.  It also has its
original lacquer, showing modest wear from a previous owner
who obviously took excellent care of it.  This is exactly as I
received the trumpet, needing no repairs.  The over all length,
not including mouthpiece, is 19 1/16" (18 7/8" from bell rim to
bell curve), the bell rim diameter is 4 3/4" and the bore
measures .460".

The cornet shown was built about 1941.  It has been refinished
but is otherwise in excellent original condition.  The explanation
for its perfect state of preservation that was told to me is that it
was never lacquered originally but given to the case maker
(Lifton) as a model for making the cases for Olds and retained
by them for many years, even after the Recording cornet was
redesigned.  The mouthpiece shown is from the period, but did
not come with this cornet.  The nickel silver "Tone Ring" was
hand engraved on the earlier Super models as apposed to the
stamped lettering on the later instruments.  The length, not
including mouthpiece, is 14 1/4", the bell rim diameter is 4 7/8"
and the bore measures .465".

The last photo to the left is a nickel silver tag that labeled the
prototype or shop model Recording Model cornet valve section
when it was redesigned in 1948.  A portion of that valve
section still exists in my collection, but was unfortunately
mutilated while still in the Olds factory.
