It's a 1951 "No Caster" with a 2001 Custom Shop replacement "thermometer" case.
Notice it doesn't say Telecaster on it? That's because Fender had received a "cease and desist" letter from Gretsch because it had been originally called a "Broadcaster", and Gretsch had a drum set with that name. Fender just snipped the Broadcaster off the decal until they came up with a new name (Telecaster). When I bought this guitar you could get it in any color you wanted as long as it was yellow, LOL. It has a very different wiring than new Teles (and even subsequent 50's Tele's) in that it has no tone circuit. That lower knob on my guitar actually blends the neck and bridge pickup. They changed the circuit in 1952 to a tone circuit with dark neck setting and again in 1960 or so to the modern circuit. This blend circuit is quite unique and cuts through the mix because there is absolutely no treble roll off in any of the switch positions.
They make a Custom Shop "No Caster" reissue now, but with the 1952 (no blend) circuit. In many ways I wish I had the newer re-issue because the re-issues have 9 1/2 radius necks with medium jumbo frets and mine is the stock 7 1/2 radius neck and those awful thin frets, LOL.
