Based on other shouldered 116Bs I've seen, I think you're correct that Van Dyke brown (which looks great on 1934/35 Philcos like the Butterfly) would be too dark on this radio. What you've done there looks spectacular.
I have quite a few radios w/manuals. Unlike almost everything else, I never did an inventory of which radios have them and which don't. Not that I am the kind of person that reads a manual anyway - -
