This machine should be rightfully called the "Oxford Talking Machine". It is a model BV with a detachable rear horn mount installed, the BVT uses a screwed in rear horn mount like all the other Columbia "T" style machines. The Oxford was sold by Sears, Roebucks and Co. between 1908 and 1909, price was $12.00.

The machine is one of the smallest made by Columbia, similar in size of the model "AA".

The removable rear bracket is attached to the box by way of a metal bracket that clips into the lid latch slots on the sides of the bedplate, the rear bracket then clamps to this bracket.
