The Cello bow Jimi Page used with Led Zeppelin in the 1970's was made in behind the "Iron Curtain" during 1970's. Each Cello bow contained a pearl dynamic thus making the shaping of the Cello bow itself. It is a unique shape made for Jimi Page himself as per requested. An authentic Jimi Page 1970 Led Zeppelin Cello bow, has an inscription of origin on the Cello bow. Jimi Page and those close to him would know the manufacturer of origin. The manufacturer had their manufacture stamp on each 1970 Cello bow from the 1970 "Led Zeppelin era" for an easy importation to the UK for Jimi Page as Led Zeppelin. This is the only way it can be authenticate today, along with the dynamics of the pearl shape and the Country of origin for importation.
