Over a month ago I started documenting all the descriptions and serial numbers of all my guitars as I wanted to update my Home insurance. I have about 10 guitars, many vintage such as my 79 Les Paul, a 64 ES-175D and others. As I was looking for a 91 Gibson OP-25 that was a birthday gift when I turned 39, I couldn't find it ... I was in a panic looking all over, thinking I left it at church where I play a lot or perhaps left it in my truck which had gone to the body shop for repairs, went everywhere I know ...nothing.... sadly, I assumed I had left my truck unlocked and someone had took it. Today (Feb 10) I got a call from Enterprise Car Rental who asked me if I was missing a guitar - WOW! seems a customer who rented the car just after me (which I rented while my truck was in the shop) found it in the trunk and returned it. It took Enterprise awhile to figure out who was the previous renter was so lucky me, The guitar I've owned for 25 years is back and am feeling so thankful right now. It's a great little guitar and I love playing it. THANK YOU ENTERPRISE - YOU ROCK! (as well as the guy who brought it back - I'm trying to find out who that is so I can thank them properly) So now, I'm trying to find out more history on the guitar itself. It's a black lacquer flattop 6-string acoustical with a Epiphone EQ and pickup under the bridge; it has a plastic round back. I still have the sales receipt showing my wife had paid almost $700 for the instrument. It came out of the Montana plant and I had read somewhere that only a couple hundred were made, mostly out of parts from another model they were 'experimenting' with. Since my 2014 Vintage Guitar price guide doesn't list it so I'm curious if anyone can steer me to a site that can give me good info so I can value it properly (from now on). Can't seem to find anything on Gibson's official site. Thank you for allowing me to share!
