Barn has text on it, I am not able to read most of it, but the first line appears to be a year, the second line has a 5 character word followed by a 4 character word, the third line says "Stock Farm", and the final line says "Lloyd" followed by what is likely a last name. Perhaps someone local to this area can comment as to who would have farmed here in 1976 or earlier.

It appears to say Lloyd Weisensel
