Lantern is functional and in good shape for its age. Ventilator is in excellent shape. This is a marriage of what I think is a Model 200 Lantern and parts from a 1954 200A. Ventilator, globe support base collar, fuel cap, ceramic type jet, and globe are from the 1954 200A. I put a new washer in the red fuel cap but will also include the green fuel cap from the 200. The only date stamp that can be seen is an 8 for August and I'm not sure what the two bumps mean where the date would be.
