thank you both for sharing your knowledge. our upright qualifies as an antique (restored by a top technician, it plays well with a big, rich timbre) with an unusual set up for a very rudimentary music holder, just a low raised rim above the fall board, not actually part of the fall board like many other uprights. 'improving' it would mean removing the original and mounting a wider ledge, altering the front facade of the case, which is fairly ornate carved walnut in the late 1890s fashion. the old school hanging desk like the one on the Berliner piano would be very compatible.
thus, appreciate very much the offer of Indianajo. we live in northern California, and if you're ever in the area you should play our 1919 Mason & Hamlin BB.
