Does anyone know the diameter of a lead main going into the kitchen 15mm
copper pipe ? I need to replace the stopcock and wondered what the lead
side fitting size is.

Have a web search for lead pipework and you should get hits to help on this.
Old lead pipes are measure in pounds (lb), so they have figures like 7lb
lead, 9lb lead and such like, and old lead mains came in sort of three
standard sizes. The first being 7lb lead, the second 9lb lead and the third
was 12lb lead, depending on what water supply was in your area.

There are fittings called "Lead Lock" which form a compression joint on the
lead and the copper/plastic pipes. These are expensive and you really to
know what size lead pipe you have before buying one.

Try the web search first for more info'
