F47 Hubcaps

[100550dvr]

Another question regarding our 1950 F47 pickup truck. Found it in the Flin Flon area and it had not been on the roads since 1978. We believe the hubcaps are original. I have attached photographs depicting their shape and configuration. They are unlike the reproduction hubcaps available on the market. I was told Ford US shipped surplus parts to Canada. Were these hubcaps used with earlier model automobiles? Any words of wisdom would be greatly appreciated.
