Dating gibson pickups
There are two basic components to your Les Paul question: dating it and identifying it.
I’ll start with trying to date the instrument, but keep in mind that dating and identifying Gibson guitars typically go hand in hand.
My overall judgment is that, while these guitars are of higher collectible value to guitarists because of the affiliation with, and use of the name, Gibson, this byno means is a testament to it being a better instrument than other brands.
While somewhat confusing, you can determine where your Orville or Orville by Gibson guitar was made, the year it was made, and even the month it was made,by looking at the back of the headstock.
There were 5 different methods used to date Orville and Orville by Gibson guitars and two factories involved withbuilding them, so I've developed the simple chart below to assist you...*F = Factory: G, J & K beginning the serial numbers denote that is was made by the Terada factory: the "G" ink stamp means the guitar should have Gibson USA pickups, and "J" for Japanese pickups.
The domestic models had the Gibson open-book headstockdesign while the exported models were given the usual Epiphone design.
The regular line as well as their "Elite" line of guitars were all made in the samefactories as the Orvilles and Orville by Gibsons.
