Quick question

[mFrame011]

Most of my m frame lenses have a date in them. Usually something like 031804. I have one lens that says NT1. Does anyone know what that means? Thank you.

"It's likely a production code or batch" (Credit @Rustpot as I asked him that same question about NT1 a while back).

I have tons of lenses and most have date codes, some have a QR code looking code etched, some have nothing. Some at the top of the frame and some are hidden where the nose piece goes.

I have some marked that way, not sure what it means
