I am sure Coupe de stylo is correct with his knowledge that the "Kangaroo is German and by Max Traut product number 95." Also, it is fascinating that such nice German lampwork was found in a house of a family member of the Swingewood house, famous in Stourbridge, for their lampworking, not at all in the hollow Bohemian style, along with a pair of "very Swingewood" lampwork horses! A nice story there, makers often admire the quality work of their peers it seems!
