Look for date codes on the parts inside. If yours is a blackface, does it
say “Fender Electric” or “Fender Musical Instruments”? Fender Electric is
pre-CBS which means 63 through early 65. The Jensen is date coded. Look
for numbers around the edge of the speaker. You’ll see 220XYY, where 220
means Jensen, X means the year of manufactuer and YY means the week of the
year. Consequently, 220718 would mean the eighteenth week of 1967, or
1957. If there is no 220, it is not a Jensen, but probably an Oxford.
