Thanks for the promotion!
Usually I would be keen to get involved as I normally visit Dorset regularly to see my father, but in the present situation I cannot.
I am also a little reticent to get in much bulk low grade stuff until we see how the market goes once restrictions are lifted. I suspect I will be inundated with people shifting their low grade collections in order to release much needed funds, and there will also be fewer people adding to their collections for a while. (High grade stuff always finds a home, but low grade needs the enthusiastic amateur with money to spend...)
I suspect @Weaver would do better selling at a local auction where there is a good chance of getting direct to a new collector - Elliotts in Wimborne or Cottees in Poole would be my choices.
I won't say anything directly about selling to the Ingrams, because I have had no direct dealings with them, as long as @Weaver has taken time to read the previous discussions on the subject of that particular dealership.
