Anyone know about these alloys?

And what they originally fit? They are Revolutions Marcos 14" x 6j. I measured them at 108mm 4 stud PCD with an offset of between 23/30 (according to the stamps on the rear).
They were black and silver.

I suspect a Marcos Mantula. Here's one shod with the 5 spoke version. http://www.youtube.com/watch?v=-jx9_F0ILqY&fea...

...at least they should fit to any cars using 4-stud Ford hubs (108 mm PCD)

I have never seen a Marcos fitted with the 4 spoke variant on the 14" - they are always 5 spoke. I have seen 4-spokes of smaller size on Mini-Marcos. I had always assumed that all 14" Revolution wheels were 5 spoke.

They are the original revolution wheels, the 5 spoke (RFX) came later and yes they are Ford fitment at 4x108, should be fitted with sleeve nuts too.

Definitely not RFX. Original 14" Revolution wheels were 5 spoke on the Marcos Mantula (I should know as I have got one, and I have two sets of wheels). Mantula is 1984 to 1992 - the Mantara that followed had 15" wheels, and the earlier Marcos cars were 13" wheels. Of course the Marcos was still available as a 'component car' in the Mantula days, and owners who chose to build their own were at liberty to choose different wheels, e.g. Cosmics, Minilites, KNs etc - but the Revolution 5-spoke seems to be the most common.

Maybe the 4-spoke 14" wheels were made sometime in the 1971 to 1984 period when Marcos weren't in business.
