Understanding abbreviations on passports?

[Em 1]

Please can anyone help me decipher the codes on my horse's passport? I understand the main ones but there are some that leave me stumped I've tried searching several sites but they all just give me the general abbreviations and codes.

E.g. Horse 1 123456 ISH MAIN STB

I think this means that Horse 1 is an Irish Sports Horse registered to the main studbook under the number 123456. However, what do these mean:

Horse 2 (AA) APP
Horse 3 TB APP
Horse 4 A AR

I've reproduced the way the initials are laid out in the passport in case that matters. Please help - I've been struggling with this for a while

i'd be inclinded to ring passport people, they issued it so should know, you'd hope

tb could be thoroughbred though wetherby's is for purebreds
aa could be anglo arab

good luck
