Hi and welcome.

Pictures of the whole thing might help identification too.

I'm afraid I don't know the mark myself, sorry.
You seem to have used your email address as your username - we're going to have to ask you to change that, to prevent you getting harvested by spambots.
I'm going to report this to a moderator, to ask them to help you fix it.
Don't worry about it!
Thanks for posting such a good clear image, directly to the board. That is much appreciated.
