At this point in time I would narrow it down to:
Model 148, Four engined monoplane flying boat for Pan American.
and
Model 150, 40 passenger ‘Streamliner’ flying boat
but I have no pictorial evidence whatsoever to confirm this.
Perhaps it is a design that never got a formal number.

Hi,

there is unknown 100-passenger transport project for Martin and it
had an estimated weight of 125 tons.

Hesham's 100 passenger Martin design is very odd.

The passenger size, six buried engines, and double-decker layout all smack of the "Lindbergh Specification" (Juan Tripp's nonsensical bit of street-theatre for Pan Am). Boeing, Sikorsky, and Consolidated all contributed designs (although the latter was actually a four-engined concept).

With the M-130 Clipper experience behind him, Glenn Martin denounced the "Lindbergh Specification". Could it be that a Martin concept was drawn up for the Pan Am "competition" anyway?

"...Gun turrets fore and aft ,along with a retractable belly turret, were considered...

With regards to that statement, I would expect true dorsal and ventral turrets, similar to the
one in the nose, not just flexible guns, which at this time already were regarded as inferior
to powered gun positions. 
It takes a long time, before all mistakes are made ...

The Martin 150 was the 40-passenger Streamliner (presumably an enlarged version of the 20-passenger Model 143 Streamliner that was specifically for Pan American Airways).
So far I have not been successful in locating a picture of these two projects...

The text doesn't sound like it. "Two aircraft in that category [which I think means: the monoplane type tested by NACA] are currently being produced by American manufacturers." It doesn't say that the NACA designs represent these (otherwise we would also see the S-42 in the drawings I think).
