Linhof Leveling Head II. I bought this to use with my Linhof Master Technica 4x5 a year ago and has worked flawlessly. Buttery smooth and just perfect up to that weight with even a heavy 150/2.8 or 90/4.5. Selling it only because I'm shooting 8x10 and it's not quite able to lock down at extreme angles with really big lenses (360/6.8). It’s in great condition. Only minor rub marks. Always stored in a case with only mounting for a shot then back in the case. Includes Linhof plate and the included plate screws for 1/4” and 3/8”. Includes Linhof box as well. $800 net to me.
