Pretty sure the only models/ranges with a nitro finish in the current range are;
MIM Classic ‘60s Lacquer (there’s a non-lacquer version too sI you have to specifically choose this)
MIM Road Worn
American original series (MIA)
Normally, the MIJ models don’t come in Nitro finish (there are some specials etc that did, but they’re difficult to get new) BUT, there is a company in Poland who refinish MIJ Fenders (stock and custom requests) in Nitro finishes of varying styles (NOS to heavy relic). I’ve played a few of their instruments and the quality of their work is STUNNING and would come in below £1000. Example here;

Hope it helps!
