Seems to me that I remember seeing a reprint of a 1960s 113 body ad that referred to it as MB Textile. Whatever the real name there has apparently been at least 3 distinct generations of it, if not 4 by this point. What do you want to bet that the latest generation is not as good as the ones that came before. I doubt it's all still in production but it is still widely available from Hirsch Automotive in New Jersey. I think their customers are pretty much limited to those who have sat down with a screwdriver in their back pocket.
