This is what the full range of Wide Five Ford V8 Hubcaps look like, including the Accessory Spyder Hubcaps.
You will note that for 1939, Ford didn't change the design of the Spyder Hubcaps to match the regular production 1939 Ford Hubcaps, but continued to offer the 1938 Ford Spyder Hubcap for the 1939 models.
These pictures also include the earlier & late Ford Hubcaps which I have on display in my Garage. It has taken a long time to collect this lot, but it has been fun.
