Found a guy locally through another forum who was an ex-Telco installer/ maintainer, who managed to score the exact 10A2 KSU I need and the B.C. Tel-ized GTE 10A2 manuals as well. It's like Christmas! Once we finally cross paths and I set the system up, I'll take some pics in case anyone wants to compare the WE, NE and GTE/AE versions of the same KSU down the road.
It's going to be hooked up with some GTE Type 186s like I had originally decades ago, and at least one of the Government model Northern Electric 564s as well. Bit surprised to see that NE supplied so much to Uncle for Government 1A2 systems on base. I thought they would've purchased strictly WE or GTE. A bunch of the NE 564s have been showing up brand-new-in-box lately, so some forgotten Indiana Jones-ish warehouse must've suddenly disgorged its contents in some surplus sale.
