Hmm, I've got some...
TS1323
86X1 (or 1X98..)
TS1619
TS161 (or T5161..)
etc.
Seems to be generic TO-5 PNP, 30V symmetrical (alloy junction perhaps?), couple mA, 50mW, < 1MHz. Pulled from an electronic organ (of the tone divider type -- 6 x 6CG7 master oscillators for the highest octave, followed by two-transistor flip-flops for the twelve notes each of all the lower octaves).
