Sorry for delayed response, I had been out of town.
My contact details can be reached through here:
www.doubleguncraft.com(One day I will get the blog running ... one day...)
Or PM me here.
As to future books: I have 'inherited' all of Michael McIntosh's personal archives -- letters, unpublished material, research material, etc, 16 filing-cabinet drawers full. I feel confident there will be a book's worth of material in it, given his importance in the double-gun world. With the economics of traditional sporting book publishing I suspect I would pursue some sort of e-book and/or self-publishing deal. Now I just need to start looking through it all.
Thanks for the interest.
And Happy Thanksgiving to all.
