SONY ECM-250 Condenser Mic Info Needed

[carsonmacc]

Recently purchased two of these microphones, but they did not come with cables. The input looks like nothing I've see before, it looks like an xlr, but smaller. Can anyone point me in the right direction as to where I can find they right type of cables for these mics?

It sounds like a 3-pin Amphenol mic connector often used before XLR became the standard. The 3-pin Tuchel connector was another one.
