Hello Olaf, take a look at the topic link that Jeff shared. Cory did an excellent job and actually worked with the gentleman who was making them and had them advertised on eBay. I purchased one for my hipo C4 and am very happy with it. Cory helped out with great advice on “aging” it and it looks excellent. I checked and the ad is no longer on eBay. Cory may have the contact info for the gentleman who was making them.
Good luck! Karl
I have included a picture of the tag I wound up with for 6S281 just for reference.
