First, thanks to all who have responded.
Second, my apologies if I sent you on a wild goose chase.
Upon closer inspection with a magnifying glass, the number is 'J490 A' not '1490 A'. I will be poking around the web some more later today.

Anyone have links/tech sheets for an early TI transistor?
The marking on one side of the can is:
The other side of the can has the TI logo.
The box it came is is labeled for military use. Here is the printing on the box:
1 EA. TRANSISTOR
AF33(600)38975 (CDPO 149)
MELPAR, INC. (MFG/CONTR)
R240028-2 ITEM NO. 063310
My web search led me to the following conclusions:
*The '110' marking on the can is a date code (11th week, 1959), which is plausible based on the 5/61 marking on the box (which I am assuming is also a date code).
*Contract AF33(600)38975 is related to the B58 Hustler program.
*Melpar was a defense contractor during the cold war.
Unfortunately I cannot find what type of transistor was designated 1490 or 1490 A.
Thanks in advance for any helpful comments/links.
