If he’s not known here on TM you might have success via Gill Bevan at MSCC/Miscellany (hope she doesn’t mind me mentioning her!). Someone who has a Mog about 20 miles away from me, but not on TM, sent her an email and she worked out who they were talking about and forwarded his email to me. Thus I could choose to respond or not (which I did).
She is very good…
