I know that "violin pitch pipes" are still offered for sale - the 4-pipe kind to tuck in your fiddle case; but even at Jr Hi level the band/orchestra teachers objected to them, and recommended a tuning fork for those who had instruments that needed tuning.

In any "academic" or concert situation, there'd be little need for it, since all the instruments have to tune to each other (to the concertmaster or to the piano) so it would be of real use only to a student practicing at home alone, or perhaps a street-corner fiddler doing unaccompanied solo performances.(?)
