Special Markings pic request

Ok this one is really tough guys, back in the 70’s when we still had Melbourne the Carrier, many USN and USMC pilots used to train on our ship. After completing a successful landing and take off they had a special marking applied to signify that they had achieved this (story has it the marking ment “I survived a landing on Melbourne”). The reason that they got this special stamp was because our carrier was far smaller than anything the USN had, thus there was basically no room for error when landing.

So, what I am after is a pic of this special marking- which looked like a mission marking under the cockpit. Does anyone have a pic?

Thanks in advance guys.
