Most of the helmets with unit markings and such that I have seen were usually pre-war M35s, usually Luftwaffe but also some Heer examples. After the war started, this practice seems to have been largely abandoned, likely due to the danger of military intelligence falling into the wrong hands.
I recall having ONE M40 SD Luft helmet with a name rendered in white paint. I also recall seeing an Eastern Front photo with dead German trooper, his helmet laying nearby with the liner facing the camera. That helmet also had a name rendered in white paint. Both helmets' writing were neatly done in Germanic script (I assume the way German children were taught to write at that time).
Names rendered like this in helmets are rarely seen today, I suspect it was due certain units allowing this for only a short time. I base this on seeing written names on helmet skirts mostly under reissue paint (an earlier phenomenon that had been discontinued).
Subsequent naming on helmets was certainly done, but usually seen in pencil or pen (aged to aqua color?) on the inside skirt or on the liner. This could be done in the field without the need for elaborate paint cans and paintbrushes.
The renderings seen on helmets touted to be authentic today are sometimes with odd colors (black/red/yellow) and/or in block script (not Germanic script) and often sloppily done.
I greatly appreciate and respect all the lot number work you've done which has been of significant benefit to the hobby. I would not try to dispute that work, except for a glaring inconsistency requiring correction for the knowledge base, and only if I was on solid ground based upon my familiarity with the subject matter and a supported argument. However, in the post above, which seems to drive your position, you don't show experience in in the realm of "named / FPN helmets." I've been at it awhile, I have many, and a good bit of experience with them. Back in the day, even now, I would buy M.42 helmets with a name in the rim, a name in the liner, both, or nothing, for $100-$150, it didn't matter. Those same helmets are $1000 - 1500 today, with a name in the rim, a name in the liner, both, or nothing. The above is grossly incorrect and inaccurate, to the extent that to allow it to remain unchallenged does harm to the knowledge base. It appears that you are adopting your observations as fact and then building upon them to refute the originality of the helmets posted here. While that's your opinion and you are free to have it, that's a highly flawed foundation upon which to build such a premise. See Post Nr. 36, supra. I've literally forgotten how many named and FPN helmets I have now, much less those that have passed through my hands since the early 1980s. It is a large number. I've posted 13 here in this thread alone. I can post many more, but I think the point is made. Again, I doubt I've never paid more for one than the helmet would be without it. I have several helmets where the names and FPNs were period removed and left sterile or new names and FPNs added.
That people can fabricate and add names to the rims of helmets to make them more desirable is without question. The ebay one does not look ridiculous just because the helmet is postwar. it looks ridiculous because the rim name looks ridiculous too. What is being ignored in your analysis, which does not support the apparent general narrative that helmets with names / FPNs in rims are ipso facto fakes, are these facts, which are necessary in the holistic evaluation of a helmet. I'd like to see these addressed:
1) Example: if a M.40 single decal helmet with no name and no FPN would easily sell for $1200, why would someone hump a name and FPN in it, not hype that, and sell it for $1000?
2) We now know that Ken N. got one of the helmets of his pair from Larry, many years ago. Did Ken N. then hump another helmet to match it? He could not have humped both. If the humper did both, why would the humper sell two helmets, many years apart and not sell them together for a big profit like Ken N.?
3) It is pretty obvious that my helmet and Larry's were done at the same time, but not by the same person (see red paint residue, style, etc.), yet turned up about a decade apart. The same humper did both? If so, why did I not pay a premium for mine and why wasn't it advertised and sold with the unit information? A "scam" where the humper makes no money?
4) What of the relic helmet found in France? It was humped? These helmets were copies of the French helmet even though the French helmet turned up later than some of these? Time machine? Or was the French relic humped to match one of these?
5) This nebelwerfer unit is not the only one serving in the Normandy AO. It is one of about seven of them and not the most engaged. Why hump this nebelwerfer unit FPN and name and not another? If you are going to hump it, why sell it for no more than the helmet and not advertise it with the unit information and ask more? For that matter, if it's so easy, why not hump a really cool unit FPN and a KIA name associated with that unit?
By not addressing these facts and focusing on the narrow premises that : 1) named/FPN marked helmets are rare if not early war; 2) Multiples of the same FPN in helmets = fakery; and 3) names and FPNs are easy to fake, therefore these are fakes even though I haven't examined them and can't explain the logical inconsistencies in such a premise. If it stops where you stopped it amounts to "Thread Seagulling", that is, hovering over a thread, flapping about, shrieking, and pooping on it, then flying off.
Edit: Here's another one of mine, a camo. I probably have a half dozen or more of this camo style. Did the rim humper copy the name in the liner with a marking pen and then then give Bachmann a promotion with the painted rim name? It's a M.40 helmet, I think a 1941 produced helmet, so it clearly wasn't done pre-war, unless it's fake. I paid no more for the helmet with or without the name, though I bought it because of it. Someone humped this painted rim name (with a promotion) to sell it to me for a little less than the helmet retails for without any name in it? Please note that this is one more of my helmets added to those depicted at post nr. 36. I have more. Names and FPNs in helmets aren't rare (desirable to me perhaps) and none of these is "pre-war".
