I have been searching and searching, and I CANNOT find this font! Please help...thank you!

I believe that is hand lettering, not a font.

Yes, they say it’s hand-painted. Might be based on a typeset sample though. 

As always with these fonts: Anyone should be able to find a suitable font in that style here: https://creativemarket.com/fonts/script/

Shucks, I really liked that font...I guess I'll just have to find a different one. Thanks for your help! And now that I know, I'm noticing that some of  the letters aren't the same. Should have looked more closely before...

It may be handpainted, but I doubt it—the typeface appears to be Isabella Script, using some swash alternates.

I just set the above text is Isabella Script - it is an exact match. Obviously the sign is hand painted based completely on Isabella Script.

I suspect that it was silkscreened onto the wood, then gone over again by hand (the crossbars on the |t|s, among other strokes, are thicker than the typeface’s for instance) to give it the appearance of something hand painted.

Correct or simply traced out onto the wood then painted. Isabella Script is a beautiful script with some very nice ligatures and alternatives.
