Hi Roger

If the needle is labelled 423 this is a needle that was supplied by Beck 
Distribution Comp.  This needle
is equivalent to a SU UH needle.



If you have the su book, then you have the taper measurements.
Measure the thickness of your needle at the tip and bottom end and a few 
points between and find that needle on the chart.

If the needles are in good shape, why change 'em?

Sent from my iPhone, so autocorrects may have inserted some odd words.
