No problem, Ron. Your work is stupendous and it's my pleasure to assist you in ANY potential eye-patch-wearin'-Indy diorama. I'll let you know when I post Part 2 of the eye injury. (George Hall as Old Indy may not be physically believable as an old Harrison Ford but when their faces are superimosed upon one another, it's amazing how close they match up.
A timeframe for the wound could be anywhere between 1959 and 1979. That'd be my guess.
