More common examples include Birmingham (left) and the Montgomeryshire Imperial Yeomanry (right).
The medal I want show today is one rated by Bill Hibbard as R3 (two to four known) and second only to R4 "only example known" - the tribute medal issued by Norton (or Norton Malton) in North Yorkshire.
The medal is silver, 36mm in diameter and made by JR Gaunt & Sons, Birmingham. The medal contain hallmarks for 1903. Hibbard indicates 2-4 were issued - on what basis is not known. Judging from the meorial to the survivors there must be 40 medals, which on Hibbard's scale rates as common - survival of the medals today is another matter. Hibbard only identifies one recipient: Trooper 12309 CP Benson (Yorkshire) Imperial Yeomanry. From my searches only two are known to exist.
The medal illustrated was given to Gunner 51107 H Kilvington 82nd btty Royal Field Artillery. Herbert Kilvington was born in "Malton" in 1868, he enlisted into the RFA at "New Malton" in 1885. Herbert served in Burma (IGS medal and clasp Burma 1889-92). In South Africa he served from January 1900 to August 1902. In 1901 he transferred from the 82nd btty to LL section pom-poms. For his service he was awarded the QSA with clasps for Cape Colony Orange Free State, Transvaal and Laing's Nek and the KSA with two date clasps. After the war he worked at the North-Eastern Railway dockyard as a labourer. In 1896 he married Elizabeth, they had no children on the 1911 census. In 1914 on the outbreak of World War 1 he re-enlisted for the Military Police but only served 27 days. Herbert died in Hull in 1942, aged 74.
