I honestly do not know where you might find recording disk blanks.

In the previous Phorum post you linked to, did you write to the fellow who listed his email address?

Well I have good news You can still buy blank records to record on. We restore and sell record cutters all of the time. Obviously, we have to test them before we send them out. We have several blanks that are Philco brand and they work fine. The best ones to use are the cardboard base discs. They won't ruin your cutting needle. The aluminum discs are heavier, but much more delicate to work with. You need to have depth set correctly to use these. The acetate on the NOS Philco discs we use is perfectly fine. They are stored in all different temperatures and no problems. If you would like the recording done for you, contact me at tse1968@45honcho.com and I would be glad to help you out.

He works with phonographs all of the time, so I believe he would be in the best position to help you out.

Your grandmother's set is probably a 1941 or 42 Philco with Beam of Light reproducer and the optional record cutter attachment. As far as I know, Philco did not install record cutters into any of their postwar sets.
