This crate was originally shipped via the Railway Express Agency, who were the precursors to companies such as FedEx or UPS. The remains of the prepaid shipping label are still visible pasted on the lid. Below and to the the right of the letter “Y” in the word agency you can see the numbers 12 and 7-30 in parentheses. The 7-30 indicates the month and year that the label was printed. While I don’t know much about typewriters and how how long an older model may have sat in stock; I can pretty confidently say that this box and it’s contents would have been shipped to either it’s new owner, or possibly a department store no earlier than July of 1930, and likely no later than sometime in 1931 as there were constantly new sets of labels being printed.
