I know the finish had changed to poly on strats but is that the case with the musicmaster/duo sonic bodies? It is said to have lots of finisg checking which I attribute to a nitro finish. Also, it seems possible that this could be a leftover duo sonic body because of the routing? Any thoughts? I'm chomping at the bit for parts to start arriving.
I also ordered some shielding paint from StewMac, something I've never tried before... any tips or suggestions?

Welcome! Looks like what you have there is a Duo Sonic II body. This was the final version of the original Duo, produced from '64 to '69, and basically the same as a Mustang body aside from the trem. Fender ended production after that, most likely because it was cutting into Mustang sales and/or wasn't selling as well as the Mustang.
It looks like poly to me. Poly does age, especially those early poly Fender guitars, which typically don't have as thick of a finish as a modern guitar. And it will check under the right conditions, though the body you posted doesn't appear to have any checking. If you want to know for sure, get some nail polish remover and put a very small dab of it on a rag. Then touch an inconspicuous area, like where the bridge would go. If it does nothing, then it's poly. If it starts to feel gooey or sticky then it's nitro. Just be careful.
IMO if you're going to do a mod as permanent as a string through bridge, don't do it to a vintage body. Get a Squier duo or an MIM Duo and put your vintage neck on it.
