If you do take the bb out then you wouldn't be able to measure the threads accurately as you sound like you've mashed them! If I were you I'd leave the bb in and just sort another frame when you've found the right thing. I quite like my bike and it runs really well but I'm starting to get annoyed with all of the little bits that make Raleighs so bloody awkward! I may well end up replacing the frame, or even the whole bike if I see something I like.
Even if he has knackered the threads a threadless BB will be fine. Seems a shame to change a frame you're otherwise happy with over limited BB choice available to you.
