Great dark rusty patina. 

From the 1930s, Google Lens tells me. 

Please note that the US Postal Service and all other package delivery companies have raised their rates significantly due to fuel costs. ALL shipping costs have gone up. I will ship the cheapest way possible, which MAY mean FedEx or UPS. If you have overpaid for shipping (eBay estimates are often high) I will refund the difference to you. 

Also, the post office is currently offering cheaper shipping prices on heavier packages (WTF?). So if I can add weight to your package to get a cheaper shipping rate, I will. And I will refund your shipping overpayment to you.
