Great, that they have it in their set. Not so great that this information leaked through ...
It is visible in a few photos. The most prominent of the photos so far published is the famous one of the Hitler visit. He's in the foreground, we look at his back and his arm ist raised.

Just above Hitler's head is a dark V-shaped object visible, right under the searchlight platform. This upside-down "V" is the trailer without the wheels. It is believed that the trailer was a "Sd.Ah 51" (
Sonderanh�nger 51 ==> lit: trailer for special purposes) used for the 2cm Flak 30 and 38 (Heeresflak ==> Army AA Gun ).
The weapons had been mounted on three small posts each on either side aft of the aft artillery director station (visible in that Hitler photo as well). The three posts for each weapon are still present on the wreck.
I have no idea where they put the wheels. It appears to me that they had to be removed from the trailer as they may have been simply in the way for fastening the trailers to the bulkheads.
The reasons for the trailers being on board are quite speculative, but I think it had to do with handling procedures for the weapons. If you move the weapon to another destination, don't leave the trailer behind. Perhaps is was planned to take them down from the ship in France, and then you need the trailers for shifting them around...
