Hi Denise and Welcome to the PSUK Forum.
the ring details you have supplied don't seem to include a year indicator. Normally the year is written as a 2 digit number and sideways (that is it runs from edge to edge of the ring rather than round it).
I would say, the breeder was NPB, and the bird was number 19 of that batch. What the other info suggests I can only guess, perhaps it is a pot code, or member ship number of a particular society.
Can you provide is with more info on the ring, type, in that is it closed or split, size (well what bird is it on) and colour.
If God had intended man to fly, He would have given us wings. Instead He gave us Parrots.
