The outer diameter of my lead pipe is about 3/4" but
how can I tell which poundage my lead pipework is?

Lead pipe sizes are the bore, not the OD. The weight is lbs per sq ft, form
which you can work out the wall thickness, if you really want to. A pipe
that is 'about 3/4"' is probably 1/2" x 6lb, which comes out at around 0.7"
OD. Pipe that is 1/2" x 7lb is nearer 7/8" OD.
