A thing that adds to the Ross Rifle-P14 Confusion is that in Czechoslovakiaicon and other Eastern European Nations, the "P14" was known as the "Ross-Enfield" for some strange reason
(found this moniker in a Czech Language Bayonet Book I picked up in Prague, 1993).

The Soviets also used this name for Both The P14 ( from Estonia etc) and the Ross Rifle ( Aid to the Czar in 1916).

Australiaicon used P14 rifles with either Britishicon Aldis Patt.18 scopes or set up in Australia with AOC-made Scopes (P18); the SMLE HT did not get into production until 1944, and very few were issued before mid-1945;
Plenty of photos exist of the 2/2Commandos in Timor with P14 (F)(T)...Winchester (F) rifles were preferentially used (F==Fine Micrometer rear sight), and also of use in North Africa and Greece.
Britain had dismantled all its SMLE snipers of WW I, and a lot of the P14s as well. Hence the rapid development of the No4 HT, and the recall of any P14s still in good order in 1939.

As to Aussie Use of Ross with Warner and Swasey scopes... who knows??? Skennertonicon's deep investigation of Aussie Service Rifles did not pick any up, whilst scoring "Ring Ins" like the Dutch Johnsons ( KNIL Air Force attached to RAAF) and Canadianicon No4 Rifles ( diverted to Australia after Fall of Hong Kong and used by RAAF and In training Units in southern Australia).
