Yes I've seen this photograph of Manton & Co in Calcutta somewhere on the net. As I'll be only visitng New Delhi I was interested to see there Delhi shop. If I could get some info regarding Army & Navy CSL and P. Orr address I would certainly like to pay them a visit.
I've been associated with former Indian hunters & shooters for quite long and am sorry to say but most of the members at 'www.indiansforguns.com' are story spinners rather than any real source of knowledge.
