I know Altec Lansing was a innovative company in the motion picture business. giving us the first sound systems in theaters. If I was to guess late 50's or early 60's by the pictures, can't read any of the date codes. Looking at the control knobs late 50's.

The EIA codes will be six digits before 1960 and seven digits after. The first three numbers are the manufacturer so Mallory capacitors will have a seven digit number 235 (Mallory) 235-6216 would be Mallory made in 16th week 1962. Those Altec Lansing parts will have 391-921 or it may just be 391 921. 391 is code for Altec Lansing the 9 could be 1949 or 1959 (your case 1959) made in 21st week. The knobs should have EIA codes on the back side. Those type of knobs are know as "Chicken Head" common in 50's and early 60's, more than likely made by Daka-Ware. Those knobs can sell for $3.00 to $9.00 by themselves. But I think you will have a buyer, try to precise date the item. I'm just giving you made up dates for reference, as I can't ID any of yours. 235 is Mallory's code and 391 is code for Altec Lansing.
