There's hardly ever (like this is the second one I've seen in the past two years) Weber kettles for sale locally in Mexico MO.
This was on a Facebook Swap Shop post last night. After driving about 10 blocks and "Swapping" for a $20 bill, she came home with me this afternoon.
I believe it's a 1978 model based on the embossed Weber logo and no date code. All the vents are intact. No grilling grate, poor condition charcoal grate, and it looks like they spray painted it some time ago. But a little trial with some steel wool and elbow grease and the paint came right off.
