While it was quickly dated, its language remained uncertain until Prof.Gershon Galil was able to demonstrate that it was an early form of Hebrew - containing roots commonly found in Hebrew, but which are very rare in other Semitic languages.Based on the charts originally compiled from Gibson’s shipping ledgers by author A. Duchossoir, the serial number you provided could have been used on Gibson guitars produced in 1970, 1971, 1972, 1974, or 1975.
Up until the early 1960s, serial numbers were fairly consistent, but for most of the 1960s and 1970s, six-digit numbers were used pretty much at random.
I was told to check the potentiometer date codes, which all have “1377142” impressed into them.
I read on a Gibson forum that, on seven-digit pot codes, the fourth and fifth numbers represent the date.
I’ll start with trying to date the instrument, but keep in mind that dating and identifying Gibson guitars typically go hand in hand.
I get several questions about Gibson serial numbers every day, and my initial answer is always to not expect or rely on the serial number alone to determine the year of manufacture.
