Re: Strange strat
Not MIJ. This is an 83/84 "Freeflyte" Standard Stratocaster, made in the US. Note, two knobs, and the input jack.
Very similar bridge to the (also front route) Elite/System 2 and System 3 trem on Japanese contemporary Strats. But what you've posted is one of the most maligned "cost-cutter" Fenders CBS ever made.
All those trems can work well, but parts are difficult to find.
