I believe the Bungay was a competitor to the Milbro in the UK. The originals were made of cast iron vs. the alloy of the Milbros. I've seen them pop up on ebay UK every now and then, including two that I would say were viable hunters back in the day, most likely with a good tally of bunnies under their belt. Some of the others were in bad shape due to their being corroded over the years.
Check ebay UK for some pics of modern aluminum copies; they go for about 10 notes on a Buy It Now auction. I don't have any in my photobucket or I'd put one up here for you.
