Here is some more info about what is included in the box (there are not any printed instructions.)
The wagon contains the inserts for beds, etc., which can be seen in the photo of the top of the box as well as the steps. There is also a table to hold the knives (yellow criss-cross legs and a sparkly blue top, as seen in the photo of the box front.) There is the platform and stand for the lady to lie back on while having stuff thrown at her (as nicely shown in Elaine's photo.) There is a set of 2 stickers (yellow and red stripe with the word "circus") for the front and back of the wagon.
There are 10 loose knives as well as a sprue which contains a knife holding thingie (not sure exactly how it works but I think it lets the guy hold one or more knives by the blade) and one additional knife. There are also 5 pistols on a sprue, a holster, and two rifles (one gray and one dull gold) - maybe the guy shoots at the lady as well as throwing knives at her?

The man has a blue sparkly hat, collar and cuffs (your guy seems to be missing the cuffs, Elaine) and the woman has a plain red tie collar and textured circlet (not the crown, as you already noted, Elaine.)
I am attaching a scan of the bag of weapons.
