[78-L] acoustic 78 accessories?

[Malcolm Rockwell]

I have a portable Silvertone acoustic phonograph made c. 1928 or so. 
It's 17"W x 15"H x 20"D. I want to have it refinished but I need a 
couple of things before I can finish the project to my liking. They are 
(1) a piece of original grille cloth - or a nice reproduction thereof - 
around 16"x10" and (2) a gold Silvertone decal 4"W x 1.5"H. I know there 
are old phonograph associations and folks that deal in this sort of 
thing but do not know of any.
Any recommendations (beside searching online, that is)?
