It appears as the VDO cockpit line of 52mm gauges is over. I tried to clean the glass of my old VDO gauges, I got them off and cleaned but in putting them back together I broke them. They have been in the car since purchase in Jan. 1974. In searching for replacements for oil pressure and oil temp gauges that I broke, I found them out of stock and non available from many sources. It appears they are no longer being made. I found clones on ebay that look exactly the same except for lack of the vdo font below needle. They are cheap and I ordered them to see if they are any good. I will give a review once I get them. My order for them with Jegs is on backorder, we’ll see if they become available. The moral here is Don’t take them apart, they are fragile.
