Can anyone identify these irons please…

The cavity shape def resembles callaway
I think it's the model that came out after diablo (which were red insets) so id go with X series but it's easier just to ask for another pic in focus
 
They certainly look like X18s and, unless they have, literally, been used to dig graves, the heads should be fine as they're made from the hardest material in the known universe
