Jeff, your piano is incredible looking.
If you can, you should look into getting it restored internally. Externally it looks exceptional!
Knabe made some of the best pianos in american history in its prime in the late 1800s. Comparable to Steinway, Mason and Hamlin, and Chickering!
I would love to find an upright like that! I love the fallboard/music desk as single wide piece. And the legless fronts, with soundholes in the case, really helps these pianos stand out.
