I searched through all my BoP reference material:
One of the profile drawings is from Mike Chamberlain, a drawing titled "Underside and Profile."
Another one is from TREKCOMIC.COM, a brown-tinted image that looks like a stats-chart-playing-card for a board game.
The third is a drawing by Stephen Arenburg, 1991, from his set called "Romulan Ships".
The fourth is from FASA.
The fifth is from the 1977 blueprints.
That leaves 2 that I cannot identify. Sorry.
The image I received via MESSENGER yesterday is from Christopher James Cushman. Matt must be his brother. I cannot quite read the dimensions. I think the drawing at the bottom says the ship is 351 feet long. My ship is 446 feet long.
It is not a matter of "stacking up" or deciding what is right. We all have our own interpretations. I try to document, show, and discuss all my steps within the pages.
I started with 10-foot high ceilings. That is all we ever see. I assumed 2-foot thick decks. In TOS we never saw the BoP side-by-side with another ship. In STAR TREK CONTINUES we see the ENTERPRISE "dock" with a BoP. I have images of the BoP model. I also refer to deleted scenes from the script of BALANCE OF TERROR.
From all that, I extrapolate a length of 446 feet.
Dialogue in the episode clearly states "Disposal tubes" (plural) but I have not seen anyone show more than one tube.
I will say that I never liked the smooth, even, clean feathers that everyone else draws. I simply do not see that in the photos. Some people even miss the black tips on the trailing feathers. When I made decals 20 years ago for plastic models, my art included the blemishes that you can see in my blueprints.
I do like the triple-landing-pad configuration from the 1977 blueprints. I chose to hide the edges of the ramp within the edges of the tail feathers.
I do like the double airlocks from those 1977 blueprints too. Mine are closer together, and set within the Hangar Bay.
But landing pads and airlocks, as well as missile tubes, impulse engine vents, hangar bay doors ... they all go back to the 1977 blueprints. None of these items are on the studio model.
I could discuss the shape of the Plasma Weapon aperture or the asymmetry of the sensors on the leading edge of the hull, but I will save those for later.
