Don't tell me we are fighting... again...
Darkside, you are correct. Idle speculation get's everyone nowhere... However, this does not necessarily point out that Boatbuilder's speculation is "idle". He did post a picture of a part that he thought was the correct one, and we can all presume that it is from a kit that he bought.
As far as the mystery pieces... I knew that these were parts that needed to be identified... but I had no idea that *everything else* had already been identified! I surely don't know the source of many parts. Besides, the picture in The Star Wars Chronicles of the Y Wing in construction seems to indicate that this shape of the neck was built from scratch along with the rest of the body - as it is all white and appears to be one piece. Are we sure that it must be from a kit, or an otherwise "found" piece? I have gotten kits before that had other pieces identified from it, but I ended up finding other pieces that were overlooked. Without these kits that "only a few know about", how can anyone be sure that none of these parts are in those? Unless you guys who know these kits, and have searched them thoroughly yourself say "we are sure that these parts are not in there". I didn't even know anyone knew what these kits were, as I am sure many others didn't (like boatbuilder pointing out that particular part).
Just as idle speculation gets us nowhere, fighting gets us nowhere.
Are we sure, or at least fairly sure, that these "mystery" parts are ALL that remain to be identified?
I'll tell you what I'll do. I live in Japan (for the next 3 months) and when I get back there I am taking a train to Shibuya and buying as many kits as I can without running myself broke. If there are any kits you guys are suspicious of, or that you know contain some parts... e-mail me.
Also, some of the pictures on the Studioscale Kit Scans page are down, and it doesn't look like they are coming back up. What's up with that? I'd especially like to see the M577 Command Post Vehicle.
