I have only two MIM teles. One is a Classic ‘50s that has a serial number dating to 2004 (which is also when I bought it new), and the other is a “‘69 Thinline” I bought new a few years later. I don’t know where the hardware was made, but all the screws from them I have observed were SAE threaded. The original pickups had plastic bobbins with white marker-looking handwritten numbers, and the bridge pickup had no metal baseplate. They had CTS pots and pickup switches that looked like either Oak Grigsby or CRL, I forget which. I have seen some saddle parts online, marketed/packaged by Fender, that had SAE threaded screws, but the package said they were made in China. I know some older (‘80s and early ‘90s?) Squiers were MIM and MIJ, but all the newer Squiers I have owned or seen that were made in the later ‘90s and newer were factory marked as “crafted” by other, Asian countries. Many (all?) were also factory marked as “Designed by Fender”.
