Cool little fun/funky shipping-crate , pantrwrstl , esp. since it's got all of it's components .
I think KC hit it with the lemon/lime opinion !
Oddly enough , I can't seem to read the hand-written portion of the 'date' section of the shippers lable (@ least in some way that makes sense to me) ...
I'd say somebody wanted this produce to arrive in fine shape , for top dollar @ the time.
Maybe it was for a lemonade social , hoedown, chivaree , etc. , down on the farm .....
Lettering on the crate itself suggest 1930's-40's to my eyes , but that's just my (non-expert) impression of the style/font .
I bet you a bright shiney nickle that a citrus collector would like yours (& that maybe Sunkist Co. would be a shot-in-the-dark , for dating it ) !
The 'cheapo' versions of wooden fruit crates were usually made in a twisted-wire & lathe-strip (or thinner wood) style , requiring few-to-no fasteners ... just sayin' that yours is nice , braced & hevi-duty (for a fruit-crate) .
