Stewardesses were different back then.

Yes all are 1/200, though I do have 1/100 factory model as well as several of the early 1/250? Scale 733 chrome models.
I know the 2707-300 without speed bumb bulges was pacmin, im trying to find out more about the 2707-300 with, as it seems to hold more significant history as pictures of it exist in the possession of many on the program.

How would you like to see? Two, three at a time? I can plenty more pix.

Oh wow, browsing this mega-thread I realize I've missed this ! Hope you're still around Beautiful collection...
The 2707-300 with fairings on the wings would be a 1968-69 configuration, like the well known Boeing cutaway published in AWST in 12/1968:

Can see the fairings there.
then the one without these fairing would be the "PPD" 1970 configuration, like the one published in AWST in 01/1970 (unfortunately at very bad quality...) :

That one is very much like the last full scale mockup. Note the underwing streaks are still present, but much reduced in length, that is why maybe not reproduced on your model.

Also of note about the MG fairings on these 1968/69 models, seems Boeing tinkered with different solutions for these, on lots of others ref they are shown as a single bigger fairing instead of two long ones. Like on these images :

Thanks!

I have volumes on the US SST program, the bound submissions to congress and FAA with data from both Lockheed and Boeing, most all NASA, Langley data, and other documents as well as a number of original blueprints and line drawings, only these models perplex me as I know the one style was PacMin. but I have no idea of the other earlier one. I probably need to post these on a diecast forum or something.

Here are a few more of the bulged and the lower strakes...

!!! This look like an early -300 config. !

Please please, post if you have more

This picture shows the wing which has flat bulge same as galgot-san's model.

The wing of 2707-300 full scale mockup had no bulge.

Hi!

Convair 58-9 SST Airliner 3D Model by citizensnip

The Convair Model 58-9 was a proposed American supersonic transport, developed by the Convair division of General Dynamics and intended to carry fifty-two passengers at over Mach 2. Derived from the B-58 Hustler bomber, it was designed in 1961 but no examples of the type were ever built. The...

I believe this is the shape which could cruise mach 2.7.

Boeing tinkered with the design of the SST, but even with the 2707-300, they tinkered with the wing design.
I think that the need for landing gear fairings means that the thickness of the wing has been reduced.
The purpose of reducing the thickness of the wing is either to reduce drag or to reduce weight.
I imagine that it was difficult to satisfy either the range or speed requirements with the original design.
