Built for and operated by Morris Munro & Co. and registered at Greenock. She is a contemporary of their other steam lighter "Faun". I cant find any record of her building except her date of build of 1875 but her place of build is given as "Maryhill" in her MNL entry and so an assumption is made that she too was built by Swans.
Morris Munro & Co were coal merchants who had the contract to supply MacBrayne's steamers, taking cargoes of coal from Ayrshire to, mainly, Oban. Return trips were often made profitable by them bringing slate back from the quarries on Luing, Easdale and Belnahua to meet the demands of the tenament builders in Glasgow.
By 1890 she has passed into the ownership of Howard Graham of Lochgilphead and by 1900 is registered to John Shaw jun of Cullipol, Isle of Luing. John Shaw passed away in 1917, bringhing the Shaw family's involvement with the puffer trade to an end. Her 1920 MNL entry shows her now owned by a James R Shankland of Great Clyde Street in Glasgow. Her registration is closed in 1921.
By way of a footnote, the Shaws of Luing were described by Neil Munro to be "A good family from Luing, and they have two puffers". Duncan Shaw, grandson of John Jnr's brother, tells me that the other puffer being referred to would have been the "Rachel ", owned by the McLeans of Ardencaple, Easdale, one of whom was Duncan's grandmother.
