Hi Kevin,
Thank you very much for your advice on buying and shipping, I am certain that we will do much more business as you sell very nice items mostly all with their original cases and instructions – unlike Ebay.

John ordered several early slide rules which resulted in sharing knowledge and me receiving a copy of the original instructions to the Pilot Balloon slide rule as used by he UK Meteorological Institute through out the 1930’s-1960’s.
