Any of the special mics. Lufkin made some extremely well made ones. I just picked up two on eBay , a 7" and an 8". One is the od green model, when shipped the seller took the spindles out, I found when installing them lufkin had made them with an auto take up on the threads on the mics. If you ever take them apart you have to actually press the thread in to the mic body it's kinda spring loaded , why I call it a take up. And smooth as silk they both have some working dings but no real damage was very happy to get them no boxes or standards or wrenches but price was right. $15 each delivered . I'm trying to get some too up to 12" set or maybe and odd big one to hang as a show or sign of my hobby / business. Good luck lots out there some are junk some are jewels . I'm lookin for an anvil mic and a hub mic too.
