I don't really recognize the logo but the style of the heads look like early Bogen, if so, then open circuit windings are fairly common (and not possible to do much about).

Using the record head for playback is more or less doomed from the outset as the gap will be wider hampering frequency response, not to mention the windings being different.

On the brighter side, finding an identical replacement may not be critical, as long as the head is designed for the same type of amplifier (i.e. transistor or valve). Since the head is essentially mounted on a small brass plate, it would not be too difficult to replace with something else and make it fit without too much hassle. If nothing else it might make the machine operational while a more suitable replacement is being sought.
