Thanks for helping with this Kim,

280S0041

9344

no manufacturer visible.

  the JamMan encoders are the same device
with a similar number

280S0041

9408

I'd figured
4-bit grey code absolute encoder.

So this is very useful info.

BCD isn't an obvious choice  (unless it's directly driving the numeric 
display)
but as there are 6 pins coming out of the device it's got to be right.
( 1-16 takes 5 bits in BCD )

I tried, but none of the suppliers I could find who deal with the 
public seemed to have anything.

Yes, it would be great to find an answer to this one.

Maybe Lexicon ordered a batch to their specification, and now they're
all gone, so there isn't a standard component to buy .

What would be the likely minimum order from a manufacturer?
