please help me in finding this font

Eurostile Extended  Suggested by frd 
DDT Ext Bold  Suggested by pheonix89 

Or Square 721

Mmm... I don't think it's Square or Eurostile

I was thinking of a "custom" Eurostile manually extended, but I might be wrong. You know more than anyone my Eurostile/square721 disease

Tried both in PS. Definitely not Square/Eurostile.

I trust you, Eurostile/Square Master

IT's definately a Eurostile deriviative. You could try my "Probert" font on here and see if it matches up for for you. There are a few generics in Star Trek packages as well that may be closer.

finally i found that font , itz DDT EXT BOLD

Similar - yes, exact match - no.
