Help dating old speakers


i have two old large wooden cabinet stereo speakers.

each cabinet has 3 speakers (tweeter, mid range and woofer.

i'm in the process of replacing the old speakers with new. i removed a tweeter and midrange last night from the cabinet and noticed a blue ink stamp on the back of the speaker's frame. the tweeter's read: 10-03-57 and the mid range's read: 10-05-67. i haven't removed the woofer yet.

the cabinets are filled with yellow insulation, have vinyl coated wiring and an
"increase/decrease treble" rotary switch operated by a paper in foil
capacitor.

there is no beand name on the cabinets or speakers. they belonged to my grandparents and i assume they bought them from Sears in the mid to late 60s.

can anyone help me out?
