This is unused but the outer box is poor - the contents look very good, however.  See photos.  This has some sort of powder in it you mix with water but it would be VERY old - 1960s to 1970s ??  Still usable?  I don't know.  Made in Western-Germany - found at a local Utah estate sale.  I can't find anything like it that has been offered for sale.  Ships out to you from Utah.  I ship daily!
