This is another Vertical  design or perhaps better known as a small footprint key, quite small and compact. original keys of this type are very rare, this particular vertical key  has only one main arm balanced against a backing plate with a small horizontal counter arm, it is fitted with quality ball races and is of solid brass construction with silver contacts and a wooden base although it looks very strange it is a fully working key, Vertical keys can be quite difficult to make and use a lot more brass than a standard but are great fun to make . This is a real collectors key a chance to own your own Vertical :) it would look really good in a collection of unusual keys  size of wooden base 75mm x 120mm and stands 65mm high weighs 400g   £40 plus postage
