The pictures you show in post 18 are not hand engraved or "carbide dragged". They are done by hand using high speed rotary tool of something like dental turbine or a modern NSK machine.I'm definitely not averse to having it hand-engraved, it's just that it's not easy to source
Any competent jeweler could accomplish this but your best bet would be to find someone doing glass etching on Wine glasses, perfume bottles, wine or other alcohol bottles. What you see is their bread and butter and copying signatures is quite common. Often upscale departments stores have these people on call or have them in for sales events.
