H.V.Highsmiths library looks much like mine [So much so that I had to check that mine had not walked!]The green book,"The Gun" is by William Greener C.E father of W.W. it is valuable and rare. The more familiar book,"The Gun" was by W.W.Greener and was first published in 1881.I see an early edition on the shelf as well as a repro reading copy.Best wishes to H.V. clearly a fellow spirit.
