Billingham is a family owned business formed in 1973 in the West Midlands, UK.
They originally manufactured fishing bags until in 1978 the owner, Martin Billingham began noticing that his bags were being used by New York photographers & thus started producing bags geared towards photography whilst keeping the original shape. The first bags were so popular that almost all production was shifted from fishing bags to camera bags within a year. This one is called 'Packington' & is one of the original models from the late 70's. The main body is a heavy canvas with tan leather trim & brass fittings, it has a quick release opening & the inner is padded & equipped for your camera & accessories.
And if you don't have a camera it's still a really good looking, beautifully made, functional bag that you'll have forever. I actually bumped into a lady in the city who had been carrying one for 20 years - it had aged so well, & prompted me to post this.
