You bet Tony - more to follow when I get the time. Have flown quite a lot this year, except for November - neither Paul or myself flew anything, I think it rained every day! We're hoping to do Oshkosh next year and maybe a trip to Calif, depends if I can persuade my better half that the money doesn't need to be spent on household appliances!
Glad to have you aboard. So you are partners in NC34837 at Cable Airport, I assume. That airplane has Serial #1657, which I found only one Serial #1658 later than yours, and it was derigestered in 1955. So I think you have the last known Porterfield that was built. I could be wrong, because it takes a lot of time to do the research on an airplane that went out of production in the 1940's. But, for now, that is what I have found.
Feel free to add pictures, stories, videos, and any info you can share with us.
