Vintage Britool 1/2″ drive 1/2″ Whitworth deep socket model number ED920. Proper old school quality English made tool. Listing as used but looks like it’s seen little use marks and rust from being stored for years with other items. Please take the time to study the pictures carefully for condition and sizes as they form part of the description. Check out my shop listings for lots more vintage new/ used Britool tools and other quality tools and quirky collectible items. Happy to combine postage wherever possible. A4
