Yes I like the art deco/streamlined styling too. I couldn't place a value on the one you described though as I don't have it in hand to examine nor any detailed photos. when I encounter one in a shop I first look inside the fuel fount for excessive rust, then examine the bottom for rust and any visible pinholes. I also look for any dents especially along the crimped edge that might cause it to leak and I check the burner wick raiser to see that it is functional and make sure the globe isn't cracked, the handle bent too badly etc.. The rest is a matter of cosmetics, If I find it in very good condition I would consider $25.00 a fair price. I have spent more though a couple times because they were early Embury models unused and in like new condition. Others less desirable I clean up and restore to working condition and put them into service around the yard as ambient lighting.
