The Rodda company still exists on paper in Calcutta - they have a license to retail firearms but don't. Yes, they were retailers who sold a lot of guns from different sources including W&C Scott, Winchester etc. There is a dating service for British guns here and you could post and ask them to help find records of your guns. Check out their historical records as well.

Please do post pictures here - they are always greatly appreciated by everyone.

Thanks and good hunting!
