Silence.
No more words on the record (and this is the record.)
Silence is your best tactic for now.
Otherwise, you may be dragged through depositions that will be costly, time consuming, and worse. The more words here, the longer those depositions.
Silence.
Sure you can talk about the 1938 pics and the like, the radio transmissions, the Bevington object, and so on, but as to the plaintiff in your suit, and his complaint, silence.
Not a word on the record unless your attorney thinks it may be productive.
(Perhaps he did.)
Just my opinion.
Sorry I can't join you in Caspar. My cousin in Jackson needs a visit, but wife needs me more.
Regards
Mike
