No response.
That is very strange. Hope he is alright.
I emailed Ron privately. I know him from when I was the agent for AB (he has been a customer for 15 years), and I know and play games with his brother, who lives on the Island. Ron has, apparently been unwell, losing 4 stone in weight, but he's fine now. It's entirely conceivable that his work email address is blocking some emails at ISP level (I know mine does - it's the bane of many a wargames business), and therefore I would recommend phoning him if email fails to elicit a response.
