I have 6 of these mag wheels that came with a FB car I bought 40 years ago. They are 13 x 5.5" with 3.75" and 4.0" PCD. Probably for a FF car. Can anybody identify a manufacturer so I know what I have?

The FB car is a Brabham BT21C and it did have Triumph front hubs (3.75" PCD) and the normal BT21C rear uprite and hub (4.00" PCD). The front hubs are now alloy hubs with 4.00" PCD.
