Sorry I forgot to reply to your question, I bought the brackets off EBay, the plexiglass is just cut to the length that puts that curve in it. It’s held in place by Taylor hold downs in the center through the deck and screws through the plexiglass in the end brackets. Bruce did cast a batch of some brackets that were very similar based off a set that another member has.
I don’t know if they are still available.

The only original condition one that I've seen up close and personal looked to have the remains of these foil stickers. The less faded area in the pic below is the right size. Can't say what color but, since it's '56, I'd expect them to have been the red ones.
The mid 50's foil stickers are 8" x 2". Earlier ones are sort of white; later ones red. My '54 Vagabond had the white ones.
I looked into the possibility of having real foil reproductions made a few years ago but the cost was prohibitive. I've made a few
but, another option might be a decal applied to an aluminum tape base. The ones I've seen are the down turned feather with the overlapping 'Atlanta, Georgia' script.
