FF 13x5.5 wheel ID and WTB

Evening all,
I was hoping somebody could ID these Minilite 'style' wheels. They are Aluminum, 13x5.5, drilled for 3.75 and 4.25 pcd. They have no marking whatsoever. Im looking for a pair or a full set if you have some. These were originally simply bored for sleeved wheel nuts on both bolt patterns but i installed tapered nut inserts.
Thanks, Nathan Down

They look like vintage Mamba wheels, except that the front centre looks like it has been machined with a lot of metal taken off. If it is a Mamba of some sort, they are available in England

I could be very wrong on the whole thing.
