If you can find out from the original source, what the actual drawing number is, that would be a huge help to you. I suspect that one of the three companies I mentioned would have it, otherwise you need the drawing number and will have to source it from NASM. Sourcing from NASM will take several weeks to months, depending on current research request loads. Last time I ordered from them, it took about 6 weeks total for obtaining the drawing lists that I was after.
