Hi Doug,
Yes, there were a number of snipers with the 2/2 Ind. Coy. on East Timor, issued with the .303 Rifle No.3 Mk I*(T) which has the Periscopic Prism telescope. These were late Great War vintage and appear in a number of Damien Parer's photographs and footage. Two such photos are found on page 200 of my 'BritishSniper' book.
