Cliff,
I have a '67 Tennessean I have owned nearly 30 years. My first Gretsch guitar.
I still love it but I really don't play it enough.....
I think yours is a '63.
I can tell you that the bridge and strap button are not original. They came with a rocking bar bridge. Not uncommon for bridges on these guitars to have been changed at some point. Some folks simply do not like them, or they may have issues with the high E string popping out of the bridge groove if they play "heavy".
I used to own a Country Gent that someone put a Gibson adjustable bridge on. I couldn't get any sustain out of it.
I ordered a stock rocking bar bridge, swapped out the Gibson bridge, and it was a totally different guitar. Much clearer and tons more sustain.
Your mileage may vary....
Nice guitar! Enjoy!
