The tail #'s I've been told are:

320's-

632, 638, 639, 640, 641, 642, 647, 649, 650, 691, 692, 693, 694, 695, and 696.

321's-

657, 658, 673, 674, 675, 678, 681, and 682.

It's sad for me. I flew many of these birds on their first logbook, brand new, seats hadn't even been broken in with farts.... Sigh... 😔
