value of Manx front hub

I have a wheel hub that I have been trying to identify. I have been informed it is a garden gate Manx front hub, it is conical with 3 or 4 fins, 8 inch, made of steel, no flange on the bottom of taper, spokes straight into hub. 40 spoke. I don't have a brake plate. what would it be worth. probably better to sell and buy something not so rare. I am not able to post pics at the moment. pictures are on other forums. thanks N
