I have a client who has a logo that has "organically developed" over many years and has a bunch of fonts and shapes stuffed into it and we are trying to return it to some semblance of a useable graphic.

Also we are trying to identify a font that will work for secondary signage so we want several of the letters to belong to an actual font family.

The most identifiable element in the letters is the angled central serif in the letter "E".

I am actually not 100% sure that the "S" and the "T" are even the same font, but the "E" is important.

Good Luck.
