Music Desk boards

[PJR]

Does anyone have a source for replacing those little music fall board 
desk stand boards on many console pianos such as the Yamaha U1 etc.  
They are about 24" by 3", some longer.  They get broken and lost at some 
of the schools I service.  I've looked in the supply catalogs that I 
have, but can't find them there.  In the past, I've fabricated them, but 
am tired of the measuring, sawing, sanding, gluing, painting etc.  I'm 
just looking for a generic, not factory replacement from Indonesia, 
wherever.  Anyone make 'em?
