Hello guys thanks for your kind offers I have not been on the forum for some time and just saw the replies. Unfortunately I have lodged the rifle for sale and will be in a forthcoming sale in 2018. I did get some from Henry Kranks thank you I also ordered some from a German company Triebel but not arrived yet. I lodged it for sale as I fell in love with the Alexander henry .500 BPE hammerless in Holts Christmas auction but however it went way beyond the contents of my piggy bank/life savings !! Thanks again and I hope whoever bought it is as excited as I would have been. P.S. that 20/577 A Henry is a beauty!
