Britool Tools England 3/8" drive 7/16" single hex, tube deep socket. Model number AHD437 with coarser knurling ( I have the same model number for sale with slightly finer knurling). Listing these as New old stock, been stored for years with other items so may have the odd mark/ bit of rust here and there. Check out my shop listings for lots more Britool Tools and other quality tools and quirky collectible items.

Happy to combine postage wherever possible.
