I know that I have been collecting more parts than I should for too long but trying to tidy a corner of my garage I found a set of 12" steel wheels and I can't for the life of me remember where they came from. They have the large 500 / early 126 pcd, a raised section a bit like early 500 to mount hub caps and perforations a bit like later 126 wheels. Cross section looks to be 4.5J. I can't place them, any ideas?
