I haven’t unstuck it yet so can’t see but I have an Evolution (rebranded Mistair model) with those marks on the nozzle. I had intended on keeping it but now I have this Grafo I doubt I will especially as you can run any size nozzle/needle pairing you want in any of them. I love that and the build quality of these H&S’s all seem fantastic quality to me.Oh, the nozzle should have a single groove cut around it in the middle if it is the .15. I believe the .2 has no markings, and the .4 has four grooves. The new nozzle in the Evolution 2024 has 2 grooves.
