In design the Type 74-B is similar to the larger 44-BX, but lacks the latter’s shock mounting and transformer shielding. The transformer output impedance taps are for 50, 250, and 15,000 ohms. The windscreen is finished in satin chromium and the base is umber gray. Attached to the base is a ball and socket joint which permits rotation or tilting at any angle.
The fabric that lines the grilles is called “silk,” but originally it was 100 per cent cotton cambric, also used across the bottoms of sofas and chairs by furniture manufacturers of that era to keep bugs and dust out. The cambric was cut to size and applied to the microphone grilles with shellac, then smoothed and worked by hand with alcohol, which kept the shellac from clogging the weave of the cambric, but allowed the cambric to stick to the metal grille. Other techniques are used today, like spray adhesive.

...hangs well with my assortment of ribbon mics - AEA44 and M88, Stager SR3 and stereo SR2N, Royer 122v, RCA 74b, RCA 77DX. The rejection is very appealing in a multi acoustic instrument session. If you are having room issues, it will certainly help mitigate them.
Not on acoustic although you could for a very retro thing. Drums are an obvious but recently realises they slay on upright bass. Can also be very cool on vocals. I think of them more like "mix in mics" to add to another mic choice if you want to add that particular retro stink.
