Hey Matt,
Great to see you this morning at the shop.
For the record, we have 3 functioning Church 47 mics.
Also, somewhere in this place, we have a 'multi channel' set of what I am pretty sure are either Church pre amps or a Cinemag mixer with pres that came with the ones we bought or were sent to us as a result of having the 3 already. I recall someone telling me they were thought to be built by Stanley Church, but let me confirm that.
The last time I saw it, about a year ago, it was built in to a leather case (it pretty ratty and old) and I don't think it was in 100% working order. These were apparently made with portability in mind so they could be used on location and might have had a battery hook up as well.
Not sure, but when I locate it, I'll post some pics of it.
Rock on!
Rolff
