It looks like a cross between a 747sp and an L1011 to me.
I have no idea what it is exactly, but I'm guessing that it was an early concept for the 747, before the 4 engine design was chosen. And I'm also guessing that it was called the 747-300 because of the 3 engines, not because it came after the -100 and -200.

It was an original concept for a 747SP (dubbed the 747-3) designed to compete with the recently-launced L1011 and DC-10 aircraft. The T-tail layout was, of course, dropped, for a number of structural reasons. I don't have time to type the whole story now, but, if you can wait, I'll try to tomorrow. In the mean time see if you can get your hands on a copy of "Boeing 747-100/200/300/SP" by Dennis R. Jenkins...it's part of the "Airliner Tech Series" published by Specialty Press.

Yes, a "Bistar" was indeed considered. The name was L-1011-600. Power from two 50k lb thrust RB-524B on the existing Tristar wing. Seating: 174-200. MTOW up to 297k lb. Range: 2000-2700nm. It was basically a L-1011-500 with two engines. I saw a drawing once. Goodness only knows where...
