Does anyone know of a source for 784 MHz crystals?

I'd like to try to 'accurize' the timer in the HP-45 calculator.

Yes, that's possible. I have a HP-55 and it works, so I don't want to
cannibalize it. I'm sure there has to be some company that can custom
manufacture crystals to specs. I did try Bomar, but have not received a
reply.

** If you have done any Googling on this at all, you know that there is no such company.

Stop being such a naive PITA.
