Why does it have to be a Legacy helmet for the 501st standards? That makes no sense. You do not have to wear a lineage Boba Fett helmet to get your BH number as long as it looks accurate, I think. I do not know anything about the 501st.
I no longer serve in a role in the 501st. I have previously served there as Legion Membership Officer multiple times, totaling 5-6 years of overall work. In that role I had the final say on whether or not any given CRL was approved. So, I speak from experience with the CRL process but do not speak as a representative of the Legion today.
Disclaimers aside: They would not be likely to require a specific helmet, so much as specific features of the helmet. Dent size, small turn signals, elongated range finder side earcap, etc... If a fan were to sculpt a helmet that had all of those features, the lineage of the helmet is unlikely to be relevant.
The 501st generally speaking does not care much about the origin of a suit. You can get approved with a recast anything, so long as it looks good. So from a Legion perspective they wouldn't really care if you bought a Sideshow bust and molded the helmet. They would just care that the end costume is accurate.
I don’t pretend to know half as much as you gents know on the subject, but I think there’s a big difference, morally speaking, between someone who directly recasts a licensed, 2020 product and sells it for profit, versus someone who takes their time to skillfully replicate a 3D design to the best of their ability, prints it, and casts it to sell.
From a Disney/LFL (and their licensees) perspective both situations you describe are unauthorized copies. That's why this fuzzy notion of morality gets so tricky.
Sculpting your own has more artistic integrity for sure.
The idea of building policy around artistic integrity is, I think, fundamentally flawed. It is a sliding scale of immorality where both ends of the spectrum still fall into the "immoral" category to the outside world.
I am all for having the conversation regarding the Sideshow Bust and how to proceed with Death Watch/Fett helmets moving forward.
I think the helmets are a fact of life now. There are several makers offering them off-board, which draws people away from TDH as a resource (I have purchased one of said kits myself!). Banning them from being here only serves to weaken the site IMO.
Once upon a time, TDH was _the_ community to go for all things T-visored. I took a few years off because my role in the 501st sort of precluded me from weighing in on a lot of things for fear of biasing my decisions there.
Now that I'm free of Legion dealings I have come back to find that there seems to be more arguing about rights and lineage and preferred vendors than there is community building / shared research and crafting.
Take this conversation -- instead of all of us putting our time into nailing the colors and patterns of New Boba's weathering, we are debating whether or not people should be allowed to sell production accurate New Boba helmets. I'm finding more info about New Deathwatch on facebook and instagram than here. To me that's a long more interesting than how X person got their molds.
