if this is all of the lettering that they have left how will they know if its and exact match?
close should work fine
If those letters are supposed to be "OOM" , then it is NOT a font. You could probably start with Trajan Pro Bold or something similar and use the Roughen effect in Illustrator or something similar to get close.
