Not at all. Are there drawing from 1962 or some other year? Did he wait six years? I don't know. Lee was pretty meticulous in his work. Would it be such a big deal if pre-1968 formal drawings never existed? We need to ask Lee for the answer.

But getting back to my question, why would you think that the 1968 drawings were updates?

It just seemed logical to me that it would be. As you say, Lee is a meticulous guy and it strikes me as odd that he'd have been making these for six years without a drawing. So with that in mind, why do the drawing in 1968? It seemed to me the only reason to re-do would be a revision of some kind.

That said, there's nothing on the drawing that we can see in the screen shot that says "revision". That not knowing was the reason I posted the question.

Of course he could have just been using some sort of master pattern as the definition (such a practice is not unprecedented) and perhaps it got so worn that it was time to draw things up and drive future production from there.

As you say, the best way to answer this burning question ( ) is to ask Lee and hope he remembers (which, based on the few conversations I've had with him, he likely will).

Mystery Solved:

So, I took the liberty to email Lee Piester directly about the Centuri drawings for the LIA-77 and LIA-100 wooden launchers leg patterns and I asked Lee if there is a particular reason why the leg drawings were dated in 1968, when the parts existed six years before? Were the parts and the drawings identically the same or did they change somehow? Lee was gracious to provide an answer:

Jeff
In the early years, many parts drawings were not much more than a sketch on a napkin. Later, as we brought more skilled workers on board, we formalized the drawings. Hope this answers the question. Thanks for your interest.

Lee Piester

Kind regards,

Like ...and I was hoping Bernard was going to come out with something like..."here is a copy of the Block 1 drawings made in 1963."

Thanks, Jeff. While I would feel pretty comfortable emailing Vern (or Bill Simon) a question like that for some reason I don’t feel that way with Lee (at least not yet). I figured he’d remember.

Wolfram - nope, no earlier drawings. In this case I simply didn’t know and was curious if anyone else did.

Now everyone who’s wandered into this thread of late does as we have the word directly from he who was there .

Thanks to Lee Piester, being the gracious gentleman that he is! Now, what would really be even more exciting is to see some of those actual original Centuri napkin sketches, if they still exist! Perhaps, some might even show up at the Seattle Museum of Flight one day! I'd consider making a special trip there just to see those. Of course, there should also be plenty more artifacts worth seeing on display by then, thanks to the generous contributions of the Stine family, the Estes family, as well as the Piesters, plus, thanks to the generous financial donations made by so many to help make it all possible.

Kind regards,
