..... and here's that egg-box again in a properly licenced XL5 SPACE CITY playset by MPC. You can see it upturned in the compartment at the lower left and in the instructions sheet middle left. I can't read the sheet so still can't say what it is. Was this available in the UK and Europe as well as North America?

PS. Looking at the box art for the MPC set the egg-boxes now appear to be biuldings of some sort? If you like XL5 here's an excellent and handy XL5 vintage toy gallery.
