Gizmo may hold the answer to the two holes, looking at his cowl there seems to be a cover over the access port ?

Interesting, also an instruction decal on the back of the cowl. I don't think there would be a Pope decal there as in Popes restoration as there is such a prominent Pope logo on the front of the machine. I would like to see some better pics of Gizmo's cowl if he reads this.
