    It should be a fairly easy part to get hold of - it's a standard frequency (6 times the NTSC color subcarrier) - this one looks OK:

    http://www.digikey.com/product-detail/en/ecs-inc/ECS-214.7-S-4/X044-ND/110145

    Note that it's specified as being 21.47727Mhz - this is pretty standard since most of those crystals are specced at something like +/- 30ppm and trying to specify the accuracy down to 1Hz is basically meaningless.
