I have no experience at all using Rangoon oil, though I know it is available even today. It was used in the Victorian era, I am sure, and I have often wondered just how effective it was, and how it might compare with our modern gun oils of comparable usage? Anyone know what it is composed of, what is in Rangoon oil? Should anyone know about the history behind Rangoon oil, when its use was begun, etc., I would certainly enjoy hearing about that.
