I am saddened to hear he passed away. I'll see what I am able to do, it would be a shame if that artifact was thrown away.If I've traced the clues from his postings, the owner died last September. You might try his executor but I expect such effects have already been disposed of: https://sussexcountyde.gov/sites/default/files/RegOrders/Middleton, Darrell N..pdf
Thank you for tracing him for me, I just wish it had turned out to be a better circumstance.
