The N717CG arrived in the mail today, and since its case is severely warped and split due to water damage, I will likely use its parts to restore a couple of the other N717CGs I have. The most needed parts are there, the N143Y hook switch and crank handle, and it has a good 41BN magneto, F1G3 handset, N1G Key, and 104A coil so it will make it easy to repair the others which do have good cases... Very pleased with it. I do have probably nine of ten of them, so if anyone stops by next summer, they can take one home with them! This one was an early one, dated 1951 (early for N717s, that is)..
Alas, the ringer isn't as good - one coil of the B1N Ringer is open. I have checked it out, and may have another I can rob a coil out of to fix it, or if I am very lucky, the break may be at the end ot the coil. Nevertheless, the phone will sever as a donor to bring at least two of the others into tip-top shape!
