Qatar Pick 28-30 multiple dates [επιλυμένο]

The Numista pages for these 3 banknotes have indications that sub-numbers a & b have been used by Pick. (https://en.numista.com/catalogue/note208335.html; https://en.numista.com/catalogue/note206019.html; https://en.numista.com/catalogue/note206020.html)

p. 908, Standard Catalog of World Paper Money, 1961-Present, 25th ed., 2019 indicates the different issue dates for 28 and 29 and only one date for 30 but uses just the full numbers 28, 29, and 30 to cover the dates and indicates 2 signature varieties for each note. Bank Note Museum indicates 2 notes for each 28-30 but the differences appear to be signature varieties and dates are not mentioned other than the first.

Unless someone has a newer Krause catalogue that shows sub-numbers I think only the main numbers should appear for each version of each note.

Will

There is no a or b for this notes, I will make the changes and wait to be validated.
