Pair of 19th Century Campaign Card Tables

Victorian mahogany military card tables that have an interesting mechanism to convert to tables. The underside section that holds two end legs have to be pulled away from the underside of the top and this allows them to spring open and be secured to convert to a card table. Hard to explain and please contact me for further information. They have had restoration to this mechanism and there are some marks on the top. The baize appears to be original.
