Yeah, somebody's showing off their mad relic'ing skilz. That bridge design looks a bit too modern for a late '70s build. Plus, the whole thing looks too old to be a leftover from that period. To look that aged, it would have to be older. Lots of other indicators. I would call shenanigans, but it's not like he's asking a ridiculous amount of money for it or making any wild claims. It is what it is - an old-looking Tele clone.
