Personal looted mounts

Does anyone know where there is a list or something that tells you which legacy mounts are personal loot or in the chest/body to be looted?

I been collecting mounts since BC retail and it always throws me off that they seem to be split up. GMOD was personal loot for me I recently got but I know some have to be looted.

I try to save space and only loot what has a chance at a mount and then go to the mail box later to sort loot for money.

Thanks in advance for anyone who knows or can point me to a source with it.

Note: not sure why I am getting down voted for a question? I did google and didn't find any things that answered this prior.
