Looking for a single '49 circular VentiPort for mock-up purposes. Condition unimportant as long as it's whole. Pic for reference. Historical footnote :: VentiPorts were functional about halfway thru the first year of '49. I remember seeing one in the junkyard in the mid-'80s, with those wire-reinforced canvas hoses hanging down from them. Pic here show remnants of the same thing. The rumor I heard was owners were complaining that kids were stuffing odd & ends into the holes. 2nd pic seems to support that story; aftermarket porthole covers!
