Here is a website that has a wealth of information about microphones, many of which turn up among us.
Click on the model number or the picture for specs and sound files demonstrating the mic of interest.
The pages load rather slowly and there are some HTML gimmicks I could do without.
But it's a good resource and spotter's guide.
Thanks for the link from Craig, W3CRR.
