This wire bottom conductor's model has no hallmarks anywhere. It's unusual to see a frame bail attachment on a conductor's model. The bail ears suggest it might be a Star product. It's a single guard model with a screw fount. There's a No. 2 ratchet burner affixed . The clear globe is hand blown and shows no seams. This is a nice unit begging for a competent cleaning; it's solid and straight, and everything is there correctly. Condition: (Very Good). Dimensions: 10 - 1/4" x 7" x 7".
