I don't really know if these would sound anything like the current vm44. If the capsule were the same or similar, perhaps -- but a couple things to consider:
- From the schematic in the document you linked, the VM41 was a transformer-based mic. The current vm44 is transformerless.
- From what I gather, Milab got some large contract to provide mics to Swedish parliament or something like that. They made a version of the VM41, but with a significant bass rolloff to make them perform better as a speech mic. I've seen lots of these bass rolloff, speech-modified versions of the vm41 for sale in the used market (ebay). If you're looking at a pair of the vm41's, be sure you're getting the actual vm41's, not those that were modified for speech use (I've got no idea if there were any specific markings or badges used to differentiate them).
