Time for a bit of an update. I'm going to start working on the back GG assembly. I still need the bellows from Custom Bellows but the rest is done. So far it weights 17lbs. This is without the back. I'm thinking it should come in at 20-22 lbs. As it stands now 30" without the extension. Front has geared rise and fall, tilt and swing. Back has geared tilt, swing and shift.
