I wouldn't take any notice of the Israel story on the basis of 'buy the rifle and not the story.........' IT is a New Zealandicon Army No4T that has become worn out and relegated to DP status and then sold off in the normal course of events. DP-ing was done with hundreds (?) more in NZ and UKicon military service when the need arose for more DP rifles. DP No4T's are not common but not uncommon either. You could occasionally see one or two of them among/with batches of standard DP's Ex-No4T's could also be seen among the shorty skeletonised rifles too.

I often used to see ex T rifle S51 marked butts with plugged holes on other rifles too

I would keep it just because of its curiosity value in much the same way as I retained an ex DP skeletonised rifle. No real value but............

I have no trace of telescope 3975 or 8975 in my lists but several VERY close
