Yep ... good luck ... originals were silk-screened on tempered glass, with all of the associated costs.
I had a deal fall apart for one a while back and haven't seen one since.
There are repros on cardboard or vinyl, but I can't for the life of me remember who made them.
I suspect that you're either going to have to print your own, be very patient, or pay twobits $139 ... I'm being patient until the bezel is the last remaining piece of the project ... then twobits gets my $139.
Cheers
