I shouldn't, Icom Mic Pre-amp

Came across this Icom microphone, the 600 ohm impedance element is no longer around.
My question is, do you recognize what model Icom this came from?
I'm going to look up the model, I really am curious if this was powered by "phantom power" from the radio through the wire harness, originally this had a four pin end attached.
I am thinking of repurposing this pre-amp, I just need to power it (If it was powered beyond voice to begin with)
