I spoke with the chap at Four Ashes Garage this week regarding the remanufacture of these. This stopped a month or two back due to the cost of tooling for the stamped oval bases, but he thinks it's back on track again and may have some news in a month or two. Maybe some enquiries from others would prompt him to get going?
