I think the key point is that (historically) Kerr has been willing to share his Enterprise plans with people as long as they don't share them with anyone else. In the case of Neill, he made his 66" Enterprise kit based on Kerr's plans but then provided Sinclair's plans with the documentation he included with the kits. I know of one case where someone re-sculpted the primary hull underside of Neill's part thinking that he had got it wrong because it didn't match Sinclair's drawings.
Kerr has been able to turn a chance opportunity to make measurements of the TOS Enterprise into something he gets paid for by not openly sharing his work. It has been successful for him, so I can't argue with his strategy.
Can't argue with that. Much of the curiosity (for me) is in possibly learning of things I wasn't aware of previously. This certainly happened while Gary and Round2 openly shared their development of the 1/350 TOS
E kit. I also thought it poor behaviour when some got antagonistic and overly rude when Gary and R2 challenged some people's long accepted ideas of what the kit should be like.
Since way, way back, like many others, I became fascinated with the
Enterprise and doodled and sketched and drew her over and over and over again. I looked at the television screen and available photos intently to get my efforts as accurate as possible. I made a number of attempts to draw schematics of her. At first I was enthralled with FJ's blueprints but which turned to (mild) disappointment as realization set in that they weren't of the ship I saw onscreen.
Over the years and decades it was always interesting to learn of some detail I had previously gotten wrong or not been aware of. This certainly included the discovery of Alan Sinclair's and Charles Casimiro's drawings as well as yours,
Shaw, and a number of folk's very nice 3D models. The development of the R2 1/350 kit was the most recent gold mine. In like manner I'm eager to see if any updated drawings or illustrations of the newly restored
Galileo exterior mockup will surface particularly as Gary is researching that for the planned 1/32 R2 kit. I might have to redo my own drawings as a result.
Beyond an interest in Gary's work it would be fascinating to see actual construction plans for the 11 footer as well as the shuttlecraft mockup. It would be interesting to see if the drawings called out for something that was changed in the actual constructed. I believe MJ initially conceived of some form of radar like dome on the front of the secondary hull and this was changed to the parabolic dish (it's now hard to imagine it differently). Did that change happen at the conceptual and planning stage or at the actual construction stage? Might there have been other differences between the finished models and initial intents? Anyone who has done any 3D modelling soon learns that some things planned on paper don't always translate into 3D and this is certainly also true for physical models.
It is that enduring fascinating that fuels my curiosity.
