.303 British Line Throwing Cartridges?


Can anyone confirm the identification of the cartridges offered here? Or tell us anything more about .303 Line throwing cartridges?



According to documentation that came from Tony Edwards these are -

“Italian blanks used for line throwing as the Italian forces were re-armed with .303 weapons immediately post war, and the Italian navy has only this year “2006” put their .303 Lee Enfield’s up for sale on the surplus market. The Italian forces had a lot of SMLE & No4 rifles around the 50’s”

But he also says they are common so I would have thought $200 was a bit on the expensive side
