See my ebay ad at:
Neat parts Layden. Any idea what serial number when Ford quit installing the lined Free-Standing top that used these?
I don't think all 1909 tops whether supplied by Ford or the dealers were the same and not all had expanders. Remember that tops for 1909 were optional and of course supplied by outside manufacturers. It could be that with the 1910 model year when tops became standard that the expanders ended.
I have added detail pictures to the auction.
