I have been in contact with a company in Germany that has been reproducing Alfa Romeo data plates and listing them on eBay "oldtimerteilehandelgoch". They are going to start making JrZ data plates starting in July. Attached is a photo of my original data plate (lower) and a new unused data plate that I got from AR RICAMBI years ago (upper). You can see that the number & letter spacing/fonts are not the same. They are going to make the new repro's to match the original.
