Well since everyones telling what they are not I'll tell you what they could be. (IMG:style_emoticons/default/tongue.gif
I have a '83 Tange made Ross Pirahna frame.
Now the frame was made by Tange which the forks are not.
However the factory forks on my '83 Ross Pirhana were made by Ross or a sub contractor.
Those forks look identical to the forks that came on it.
Although not high end by collector standards those forks look to be in very nice shape.
Interested in buying a 1983 Tange made Ross frame in nice shape ? (IMG:style_emoticons/default/laugh.gif
