Thats pretty cool Jeff! Looks like my old Kenmore gasser frame. I had kind of a similar situation, I had a rustbucket Performer and couldn't justify dumping $100 into it! Used the lid for a UDS, frame for the WSM's and put legs on the bowl and now have an extra charcoal lighter.
Is that a Weber thermometer in the kettle lid?
If you want it and the gas assist PM me!
