I found an old firemens hose nosel in my back garden cn any1 please give me a bit of info about it and a value?

Those old br fittings may have a good deal of value and are often collectors' items. I'd clean it up some (no br polish though, just wash it) and ask an antiques appraiser. That said, the date may not indicate when the fitting was made, though. It may be the incorporation date of the company. You might want to google the company name to find out if it is still in business. Of course, donating it or lending it to your local historical society may also be in order, too.
