Question Regarding Volley or Long Range Sights on the No 1 Mk III

[5thBatt]

I have
1907 BSA MkIII Imported by me from Australia





1909 EFD MkIII (No2 MkIV*) My first Volley sighted SMLE, brought at a Auction & was my representative MkIII for a few years





1911 BSA MkIII Brought at a auction 3 years ago, full matching numbers & in great condition, was willing/prepared to go $1600, got it for $410





1915 LSA MkIII (No2 MkIV*) Imported by me from Australia, sold on, then reacquired back.





1915 Lithgow MkIII Brought as a sporter & rebuilt by me.





1916 Lithgow MkIII (No1 MkIIIH) Imported by me from Australia.




In my 30 odd years of collecting, i have only seen another 2 or 3 MkIIIs that were any good for sale but seen others in collections but also seen a few collections that were short a Volley sighted MkIII, IMO, quite scarce in NZ
