The R J Simmie Collection has been put together over many decades by Dr Richard Simmie, a grandson of Jock Simmie, one of the principals of Simmie & Co. The Collection contains records of the Simmie family connected to Simmie & Co and also Harpsdale, the historic rural property home of Jock Simmie, purchased in 1941. These comprise an extensive collection of photographs, construction and farm business records, artefacts and ephemera, family heirlooms, even historic farm machinery.
