J-rod:
The wheels shown on your link are MWS wheels (formerly Dunlop) and British Wire Wheels is a MWS dealer/distributor. This is from their website:
“In 2016, Classic Car Performance inked a deal with the world-famous MWS (previously known as Dunlop Wire Wheels) from the U.K. to sell their wire wheels. Under the name BritishWireWheels.com, we will be their exclusive North American distributor of Jaguar wire wheels, as well as offering wire wheels for numerous other British Cars.”
You might want to take a look at this thread from a few months ago: Dayton wire wheels or mws
From that thread I’m assuming somebody on this forum has dealt with BritishWireWheels.com - given location I think Gtjoey would be a good bet so hopefully he’ll chime in here.
