Requesting New Reference for Thai Banknotes [solved]

Dear Admin …

The reference for Thai Banknotes is a book written by Somchai Gern, and has a reference TBxxx.

Owen from TBB for example references Somchai - so for collectors of Thai Banknotes - it is the definitive guide.  Would be good to be able to add the proper reference numbers as well as the pick number references.

Info:

Thai Bankotes Catalogue

Compete Edition 1853-2022

By Somchai Saeng-ngern

Cant see an ISBN Number in the book … 

Published by Hobby (Somchai's company)

He uses a reference of TBxxx for standard notes and CBxxx for Commemorative Banknotes

I have a bit of a problem here. We can only add one reference code. Do you know any acceptable code that would work here. References would then look like this: NEWCODE:TBxxx or  NEWCODE:CBxxx

Bump.

I did that: https://en.numista.com/catalogue/catalogue.php?id=2310

Tell me if you think it works :-)
