Hi, wondering if someone can give me a confirmation whether this is “12,7-B-32” [API] or “12,7-BZT-44” [API-T].

The tip looks like purple over red to me. As far as I understand it, the “B-32” has black over red, whilst “BZT-44” has purple over red.
I’m assuming it’s the latter until someone chimes in.
