I have collected antique pistols for over forty years and my interest has spread to all old weapons and military history. Since retiring from my career in Civil Engineering I have concentrated in writing about these subjects. I have written many articles for Journals and Magazines in the UK, USA and Macau. More recently I have been writing articles for CityLife magazine under the banner of History Matters, and I am researching a book on the Peak.

I have also written two non-fiction books. The first Irish Gunmakers, is primarily a listing of gunmakers and gunsmiths working in Ireland from the earliest times up to the middle of the nineteenth century. My latest book is The Defences of Macau. Forts, Ships and Weapons over 450 Years, published by Hong Kong University Press in conjunction with the Instituto Cultural do Governo da R.A.E. de Macau.
