I was looking online for a good fluid head and stumbled upon a "Thomas Viscodyne Fluid Pan Head" made in Los Angeles, Calif. by TA manufacturing corportation. It was cheap so I bought it. It arrived today and I am quite impressed with it - very smooth motions with adjustable friction and excellent machining/ workmanship. It weighs about 4 lbs and the camera mounting plate is 2.5 x 4.5 inches to give an idea of scale. Does anyone know anything about this company or its history ?
