The Shure models that match your pictures (body style, no identifying markings, terminal pin sequence) are:
M95 (coils = 650 mH/1550 ohms)
V15IV (coils = 500 mH/1380 ohms)
SPS series 5 (coils = 650 mH/1550 ohms)
SPS series 6 (coils = 700 mH/1550 ohms)
There's also a Radio Shack (V15-RS) coils = 300 mH/975 ohms) (this model may have the "V15-RS" printed on the body.
It would help if you could get the coil measurements.
