I agree. I'd date it to March 1982. Being a tester/demonstration bottle would also fit in with that timeframe being a recently launched fragrance.I see a batch code of 9124, interesting how it's separated out. No barcode which means it's from March 1982, using ROLS website.
I've also seen those separated batchcodes on tester/demo bottles before as there's one on a Pour Monsieur tester I have.
