Based on my searches I thought about using a buzz stop because they appeared to have a similar shape. I had no idea there was an actual tuning fork inside the body. It looks like it could be machined somehow, but one of the cross bars is slightly rounded, and it would need to be gold.
Ebay is funny. I probably always feel slightly lucky when I do a quick, cursory search--not really expecting to find anything, and usually nothing happens. I felt lucky but I simply increased my odds by looking often, albeit in rare and random bursts. Most guitars could be improved with one or two little parts. This part could save a guitar from taking the neck off. I already have another white Falcon corpse I am fixing. (I started working on that one this week as well.) PICS TO FOLLOW.
