Bouldersmith,

The Rodda company still exists in Kolkata (formerly Calcutta) India as does another venerable old brand, Manton. It is my understanding that they still have retail records of guns sold by them but you would have to contact them directly to find out. It can be a bitch dealing with them because of how slow they are to respond to the most basic communication.

Rodda's descendants run a British database at www.internetgunclub.com but as far as I am aware they do not have the Rodda records available with them.
