Can't really help but looks like a truncated M22WR (50mm voice coil) but with a M21WO 40mm voice coil and motor (see attached).

An OEM cobbled together of various Vifa parts.

I will measure and compare, but forgot to bring a high resolution voltmeter from work, so will have to wait over the weekend...
