These wheels came on my W114 when I purchased it earlier this year. They are Appliance Wheels, labeled W.R Grace & Co. No sizing on the wheels, 14" diameter with a 5-6" width.
They currently have some Michelin "X" all season tires that show plenty of life left, but may be too old to drive on. Set of 4 wheels and tires, have Mercedes center caps, decent shine as seen in the photos. Located in Orange County, CA. $350 obo.
