Thanks Mehul , for the kind words!
Tinker, Ozhunter,
I had a busted up rear sight for the 450/400 Jeffery-I was quoted something on those lines when I wrote to them, asking for replacement- single fixed plus 2 folding leaf.
Had a single V machined out and fitted in, its doing fine-until i get a better replacement from NECG
Best
