Help dating my Roy smek uke

Hi I'm new here and I am not good with technology so please bear with me lol.
Does anyone in here know anything about the Roy smeck harmony uke? Or how to even date one? What it's worth if I sold it?
I can not find a serial number or much of anything about it. Thank you for any help or comment

It's probably late 1940's, early 1950's. In the '50s they started using plastic fretboards, so this is an earlier one. Harmony made approximately a gazillion ukes, and no small part of that were branded with Smeck's name.

One in excellent condition might fetch $75-100 on a good day. Yours looks a little tired - kind of looks like there's a crack on the upper bout to the left of the soundhole, the bridge slots are worn, it needs an overall good cleaning. If the back and sides aren't cracked, the seams are good, the neck joint is good and the tuners are original and still good, it's maybe a $40-50 uke.

Not helpful, I know, but when I first read the title I was going to suggest dinner and a movie.
