Standard 1/2" Compression Tee Joints, which judging by the style of the body casting and nuts was probably produced by Peglers of Doncaster - the major producer of these fittings in the 1960s.
With reference to Sausage's 'Fat' joints on lead water pipes. Years ago; you knew you were on the way to becoming a proper tradesman when you could join two pieces of lead pipe with a faultless 'wiped joint', and not end up with a pool of semi molten lead all over your boots!
it's gross, but interesting....who got to clean it up?
