Thank you Bruce really appreciate your information, as you say metallurgy was in its infancy I mean Lithgow only started in 8th June 1912 besides we were on the other side of the world from the mother country.
I've never seen or come across any info or pics of actions of lee enfields that have had catastrophic failures from poor metal the USA's 1903 had the heat treatment saga's which has been well discussed here to which I found to be fascinating with regards to what it entailed and how they found & fixed the situation.
