Here's an Ampex 1101 Dynamic Microphone from the 1960's! Ampex sold these "secret weapon" dynamic microphones to go along with their tape recorders. These microphones have nice texture for drum uses and harmonica players (best for high SPL sources). This one has been modded with a balanced output to XLR, and will need a good amount of gain for general uses. If you've been looking for an interesting dynamic option to try on louder sources, this is the microphone for you. Grab this 1101 from Ampex!
