Did Mest have a guild mark? With respect to the recent questions about guild marks, there seems to be an important piece of information missing.

A main purpose of a guild mark should be to identify who is part of a guild. When Mest infiltrated fairy tail, did he have a guild mark? Could he have faked a guild mark? 

My impression is that he merely had to cover enough of his skin with cloths so they assume his mark is hidden as no one would think to check.
No, Mest Gryder did not have a Fairy Tail Guild mark. And neither did he need one. As his ability which allowed him to infiltrate to begin with can also cover for the lack of a guild mark. Allowing him to be a Fairy Tail member, without a Fairy Tail mark.


  Doranbolt, a member of the Magic councel, used Memory Control to deceive everyone in Fairy Tail into believing he was a member of their guild named Mest Gryder.


Edit

Is it a speculation? Mainly yes but do consider the following. His power allows him to make everybody think he is a guild member. To obtain a real guild emblem he would need to go to Makarov and ask for one. Which at that time already should think that he is a member of fairy tail. Which would make it weird for him to ask for a guild mark.
