The first thing that the copy lady asked for was the "book house"!
As it turned out what she really wanted was my address to enter into the pro-forma document.
That document is NOT what you end up with, but is only used to gather the reqiuired information, which is then used to type up a letter in Thai with a (TRANSFER OF RIGHTS FOR CAR), in English at the end of it.
The girl in the small office processing it was very obliging, and when ready brought the document outside to where I was waiting. Fee: 500 baht.
To answer my own question; the document is valid for 1 month.
I will also add that it will be a sad day for Hua Hin Immigration when that copy lady retires!
I have not been there that many times, but each time that I have been as soon as she spots me hobbling outside on my walking stick, she immediately insists that I go inside and sit down.
