First off, it's probably a Tech IV or early Tech V. If the front rise is operated by a knob on the right side of the front standard (looking from the back), then it's a IV, and if there is a ratcheting lever on the left side, it's a V.
A Technika in good condition with cammed Zeiss lenses is very desirable. The usual combination is--75mm Biogon, 135mm Planar, 180mm Sonnar, so you might ask the consigner if there is another lens. The 75mm Biogon is the most valuable piece in the set. Each lens should have a cam with the serial number of the lens on top of the cam. If the camera is a Tech IV, then the serial number of the camera should also be on the bottom of the cam. If you have a Tech IV with cammed lenses, you should sell the lenses with the camera, if possible, because the lenses are cammed for a specific camera body. If the lenses are cammed for the Tech V/Master Tech, then you can sell the lenses with the cams, scales, and infinity stops, and the cams will be accurate on other Tech V's and Master Techs.
What format and type is the rollfilm back? If it's an old Rollex back with the knob wind, it isn't very desirable, because it will produce overlapping frames with some modern films. If it's a Super-Rollex back with a lever wind, then it's very desirable. If it's 56x72mm, then it's fairly common. 6x6 and 6x9 are less common. Rapid-Rollex backs that slip under the groundglass are fairly unusual. 6x12 Techno-Rollex backs are worth considerably more than smaller format backs. You can sell the rollfilm holder separately from the camera, since it's not involved with the rangefinder calibration, and will work with most 4x5" cameras, not just Linhof.

Sell the tripods separately from the camera. They work with any camera, and there is no particular advantage to using a Linhof tripod with a Linhof camera, though they're fine tripods.
