Practicing on pictures is so hard to do! But it's also a lot of fun! So here's what I get: g1-14, g2-16, g3-11, g4-19, g5-10, mainbeams-50, mass-30, added together is 150, x2 is 300, plus inside spread-40, = 340 gross....give or take several inches for my guessing tine lengths from a picture and guessing mass...
