On 4 April 2012, at Bonhams auctioneers, a rare 1 3/8in. punt gun by Wm.Moore & Grey no.2657 came up for sale. This punt gun was mentioned in "The Field" magazine on 8 May 1897. The gun was used to demonstrate the difference between black powder and S.P.C new product "303 Rifleite" at the S.P.C. range in Barwick. S.P.C. ephemera, in general, is very scarce. A small quality of original boxes, cans and munitions were shown in an article written by Will Adye-White.
