44383 A: Riding set (1983)/44570 Riding Accessories (1984-1985)

As far as TLSM can say this little pack was first sold as 44383 A: Riding set, in 1983. The year after they changed the name in the brochure to 44570 Riding Accessories 1984-1985. But the package looked the same, marked with the early numbers on the back.
