You are looking at a rarer 1974 Electro Voice 654A dynamic cardioid microphone with a low impedance setting that was sold as a quality studio model by E.V for quite a few years starting in the mid 1960's I believe and stopped production in the early 1980's.

You are looking at an older Electro Voice model 950 "Cardax" crystal cardioid microphone. I would rate the signal strength at only 30%. Most of these 950 model mics don't even work at all. The mic is better off being used for display, prop or repair purposes.

Cord is in rough condition. Untested

It's in very good condition as well. No weird odors either. I've never even seen a DuKane 7A155 box before. Pic # 2 shows this very model in an old Electro Voice catalog from the 1950's. Again, this mic was sold under contract to DuKane which was a very common practice by both E.V and Shure Brothers.

AS SEEN NEW OLD STOCK.

The 419 model stand was originally intended to be used with certain E.V models such as the 725, 726, 640, 645 and the 1950's era 644 & 664. The base is quite heavy though and makes an excellent platform for top heavy mics or mics that are angles farther outwards.

This is the E.V model 640 dynamic microphone with a heavy industrial / deco styling. It was introduced in 1945 and made in South Bend, Indiana. The 640 was sold in two versions. If you are looking for a rare Electro Voice microphone to add to the collection or simply use for a variety of purposes then you might want to consider this example.

Here's an original mic boom with microphone from a milspec headset of unknown vintage. Looks 1960s, definitely older than the military headsets I was issued back when I wore the green. Looks to be in good condition, though I have not tested the microphone itself.
