I'd recommend putting some new strings on it first. ;-)
I'm a big fan of Gretsch. My oldest is named after one of my Gretsch guitars, actually.
Gretsch is the 2nd-oldest family-owned instrument company in US history and they've made some amazing instruments over the years. The company was sold to Baldwin who did a great deal to ruin the brand by moving manufacturing from New York, losing a ton of employees, making VERY questionable decisions when it came to models, and then eventually running it into the ground. Fred Gretsch III reacquired it in the... I want to say 90s. He's a nice guy and started getting instruments made again and they were pretty lackluster. They were more vintage-inspired than anything else. It was only when he partnered with FMIC for manufacturing and distribution that they started making more vintage-correct instruments that followed the same bracings and body shapes as the vintage examples.
But it seems like once Joe Carducci retired from FMIC (he was the guy at FMIC who was in charge of Gretsch, but always under Fred III) they've started to release what I consider questionable updates. Their guitars are starting to have weird bridges and use bracings similar to Gibson. It's almost like they want to be a brighter-colored Gibson, but there are more than enough Gibsons out there for everyone. I don't know why they aren't leaning into their own uniqueness.
Anyway, their vintage ukes sound pretty killer. I'd like to get an old Gretsch tenor somewhere in the future. Modern examples don't grab me nearly as much.
It seems like you've got a lot of history in your instrument! I'd capitalize on that and learn its ins and outs and see what you can do on it!
