I whole heartedly agree with Qui-G, mostly with Gav. If AA accepted money for whatever role he had in the creation/construction of the Stormtrooper, a professional standard indicates that he has no rights to the Stormtrooper beyond what any other fan-artist enjoys today. The only thing, therefore, that distinguishes AA from TE, GF and GINO, et. al. is AA's for hire contributions to the production of "Star Wars".
That single distinction is not without value to some collectors. Myself included. However, in view of all of the information available, including what has come from various debates on this and other forums, reasonable doubt does exist regarding the provenance of AA's current offerings. I can determine that reasonable doubt exists simply on the basis of the existence of this very thread.
If AA's ab plate - as just one example - more closely matches an early TE (or a GF ab plate) than a screen-used ANH ab plate, then it most certainly is possible that AA copied the work of a fan-artist. If AA copied the work of a fan-artist then I agree with Gytheran: SDS products should not be traded at the RPF. It is, I believe, stipulated that other of AA's armor pieces are significantly different to what has previously been available. However, given the manner in which SDS has conducted operations, I'm really not altogether inclined to accept that as anything other than: other of AA's armor pieces are significantly different to what has previously been available.
Both TE's and GF's ab plates were derived from an ROTJ suit. The point has been made that the ROTJ suit comes from the ANH suit that AA formed. So stipulated. However, unless AA has access to a screen-used ROTJ suit or an ROTJ tour suit (both of which are possibilities), then his ab plate ought to look more similar - if not dead on - to an original screen-used ANH ab plate.
Here are the 2 problems. We don't know if AA has access to a screen-used ROTJ suit/tour suit. We also don't have access to a screen-used ANH ab plate for evaluation to the SDS ab plate. At present, there is no smoking gun. All that the RPF can show is marked similarity to a fan-artist's derivation of an ROTJ suit.
That is my understanding, trying to follow the facts of the armors' development paths.
If AA were a member here (and, there were no pending LFL action) he would - I hope - be asked to present proof that he either reworked a screen-used ROTJ suit, or can provide sufficient evidence of the provenance of his molds. Frankly, I'm unconvinced that AA could pass this test if he were an RPF member.
Since AA is not a member here - AND - the RPF does not possess that smoking gun indicating iron-clad proof of recasting - AND - other scenarios exist that suggest means by which AA's offerings conform to the CoC, this all comes down to an IF THEN statement that will continue to loop until the LFL vs SDS action concludes.
I believe it to be within the Mods' purview to make the call either way - allow SDS pieces to be traded or ban their trade. I'm just glad I'm not a Mod...
