This clarinet looks somewhat like the Artley/Armstrong clarinets. Maybe it was a predecessor. The clarinet has the same plastic and brushed finish of the Artley line. However key work is very different, especially the separate posts for the Ab/Eb.

Serial  #752
Barrel: 66.6mm (too long for me)
Bore LH joint top: 14.8mm
Bore LH joint at bottom: 14.6mm Looks poly-cylindrical
Approximate date of manufacture: late 1950s or early 1960s

Intonation results taken when playing loud and not lipping. See how to interpret these results on the Model Comparison Page.

For this test, I used a 66mm Vito barrel, pulled .2mm at the barrel and 2mm at the middle.
