Norton engine component weights

I am trying to document Norton engine component weights , so I asking for the following weights of original Norton pieces found in an 750 Atlas, P11, P11A, N15CS, N15CSR, G15mk11.....as they all share these same pieces - original piston stripped bareoriginal rings setoriginal pin with clipsoriginal rod total weight with bolts, nuts, shellsor even original piston, rings, pin and clips togetherYou can own a nice kitchen digital scale from a local store or EBay.Slightly more difficult , i would like a total weight from the original crankshaft from these same models ....same part numbers, so should be same crank.
