This has been my first castle set together with 6040, this makes it stand beyond any criticism.
...though it is not well balanced. Besides this it's a nice cart with a nice selection of minifigs and accessories. Back then TLC was generous enough to add an additional saddle to carts so that the horse could be ridden as well.
Like with every small set from 1984 there are different versions of instruction sheets. The first edition (at least I guess it was the first) showed the minifigures in a hand-drawn style. The more recent (at least I guess...) version shows the front cover picture with the cart hovering before an ocre area rather than standing at the edge of an abyss.
Back in 1984 I got it in the advent calendar, part-wise spread over several days. I never saw the box until I afforded an unopened copy on eBay the other year. *sigh*
