Yes, great news that she's going to keep going in his stead.
But I wonder if it may just be better to sell the moulds on. I wonder if this might not be a better way to continue his (and Navwar's) legacy.
She's not that young herself, so it's unlikely to be a long (or even medium) term solution.
And there's just no way that communications or ordering/technology side of things is going to update.
No.
It may be best to sell the moulds on to someone who can advertise, promote, trade, and keep them in circulation more efficiently.
That may be a better tribute to his life's work.
I'm sure it's hard to let go though.
