The Arms and Armour Society:

The Society was formed in 1950 by a small group of enthusiasts dedicated to furthering the study of arms and armour, from the earliest times, by bringing together scholars, collecters and professional experts. It has now grown into one of the leading groups concerned with the study, collection and preservation of arms and armour. They produce a twice-yearly journal for the publication of original research papers, and in addition members receive a quarterly newsletter.
Membership is open to all, and takes two forms: either 'Corresponding' or 'Full'. Members can attend monthly meeting at the Tower of London, and the Society organizes other events, such as visits to collections. For more information about the Society go to:
