My first pressure lamp I ever bought and definitely my favorite. It took me a few years to get the correct shade for it.
I notice that this lamp has a nickel-plated cap on top of the handle, as does this other example in the Reference Gallery: Knight Light & Soda Fountain Co #321 Sunray Lamp But this example does not have the cap on the top of the handle: 1922/1923 N°321-M with ribbed dome opal shade. I note too that the illustrations shown by @Titoo do not show the plated cap: https://classicpressurelamps.com/th...ny-2701-2729-n-kildare-ave-chicago-ill.10885/ Cheers Tony
