Thanks to Gary Kern for giving me the opportunity to review this clarinet!
New information from Gary:
The company 70th anniversary brochure does not picture or mention Mr. Penzel. The chrome plated keys on this clarinet would seem to point to a rather later date in Penzel-Mueller's history. The serial number is written vertically like on other P-M clarinets.
Bore LH joint top: 14.7mm
Bore LH joint at bottom: 14.9mm
Intonation results taken when playing loud and not lipping. See how to interpret these results on the Model Comparison Page.
For this test, I pulled1.4mm at the barrel and 1mm at the center tenon.
Intonation summary: The low register D and corresponding A could be lowered by closing the tone hole with glue or wax. The exceptionally flat low E/B could be fixed with a hole in the bell. For a clarinet of this 1930s/40s era, this is OK intonation. The clarinet comes with a lyre holder built right on the center tenon. I think this may be an indication that it was a student level instrument and that they knew it would be used in marching.
Key work quality: Good quality chrome plated keys.
This clarinet is most appropriate for: Anyone, including intermediate to fairly advanced.
