First set of Loree serial numbers: A1-Z99 1881-1910
Second set of Loree serial numbers ("double letter"):
AA1-AA99, then onto BB1-BB99 and so on to ZZ99
Third set of Loree serial numbers: AA1-AZ99, then BA1 (BA01)- BZ99, and so on... 1929 to present
So, two Loree oboes exist with a "DD" at the beginning of the
serial number stamp, though the later (modern) DD oboe
will most likely have TWO numbers after the DD, such as: DD05.
The keywork patterns of the oboes from the 1910s and the modern series -
The oboe in the photographs is a THUMBPLATE system only.
C and Bb can be actuated only by the thumbplate OR the single right hand side key. No connection exists between the lower joint and the upper joint, no connection from the F# key to the riser vents for C (B#) and Bb (A#).
A complete pain to try to play in my experience.
However, this antique DD5 oboe has a left F AND a long left C#- this keywork (in my estimation) should be standard keywork on all high end oboes.
For all the effort the goes into making the "banana key," I surmise that
a long C# could be made instead for just a tiny bit more effort.
I have recently heard of an audition for an oboe position at a major symphony orchestra where the pieceto be played for the sight reading test was impossible to play without the benefit of a left C# key...
With best wishes,
