I just sent them this. ( @GBassNorth think this might answer your question too)
"Hi,
I believe, with fair certainty, that this product that you are trying to sell as a "1976 Thunderbird Korina" is actually a 1990's Thunderbird with a natural finish mahogany. Without viewing the serial number I cannot be certain the exact age but there are multiple tell-tale signs. Some major one are
1) The headstock is fairly smaller on the newer models
2) No holes in the body from the bridge cover, pickup rings, etc.
3) Placement of the input jack, 1976 had it under the controls
4) The placement of the front strap pin is incorrect, and there seems to be no hole where the strap pin should be.
5) Granted the hardware could have been changed, it is definitely not the right hardware
I am writing you this so if can be corrected before some, unsuspecting person, purchases this, and comes back angry after they find out that it is not correctly advertised"
