A stylish bark-textured 1972 hallmarked Sterling Silver bracelet...
The solid silver hinged bracelet is typically early 1970s - with a Modernist simple shape and Brutalist inspired texture. It's fully hallmarked 'Pat No 1167637, B Ltd.' then the anchor and lion stamps for Birmingham, and the date letter 'X' for 1972. The opposite half also has the X date stamp. Made by Bracelon Ltd, the silver is Sterling 925 grade. Look at the retro linear pattern - it has random scratched vertical lines which catch the light and dark. It's hinged in two halves and opens out fully - a simple design that locks together beautifully.
It's around 18cm internal circumference when fastened. The internal oval from above is 6.1 by 5.2cm wide. The silver is solid (not hollow), is straight sided and 7mm wide. Please check that it should fit you (not adjustable). It weighs 16 grams. Slimline, flat and elegant, this would suit a more petite wrist.  
Very good vintage condition. Looks beautiful on - the photos don't do it justice. Very presentable, simple, classy, retro, and a perfect gift idea.
Includes P&P to the UK. Comes in a presentation box.
