I have been asked by a fellow postgraduate for help in identifying this case.
It was recovered from a dig in Israel in the area of the WWI Palestinian battlefields.
Case length is 60mm so it appears to be a 11.43x60R Peabody (but I am happy to be corrected on this as it is outside my area of knowledge)
Can anyone identify the manufacturer? I have my own thoughts but would like the opinion of others first.
