I now have four.As the one I found on the weekend made the forth one,they are.
1973-1974 V135 VC-Mustang (Mark IR)- Red 1973-1974 V135 VC-Mustang (Mark IG)- Green
1974-1978 V206 VC-Mustang (Mark II)- G4 No Prime (last weeks find) 1974-1978 V207 VC-Mustang (Mark III)- Remote Primer.
There is apparently a 1973-1974 V135 VC-Mustang (Mark IW)- White Top Green,but I have never seen one of these.So I'm wondering if they even exist.
I also have the Mustang that followed from these.Which was just known as a Mustang no VC in the name.Looks pretty much the same,well here I'll show you.
