Hello DD and Laurie, thanks for the additional infomation, I'll be looking to add these to my 'Wanted List'.

I have found that there is a great variation in the prices asked for the Winfer books. I ordered volume 1 (Alex Henry rifles) unused new condition, last night from a U.S.Book Dealer for US$ 45.00. Other sites here in the UK and elsewhere in the USA were asking up to US$ 160.00 just for this one volume. It certainly pays to shop around.
