Pair of Ross condenser microphones. (Top Amersham HP6)

Of a certain vintage, but worked well when last used and in very good clean condition (not tested recently, but not much to go wrong with them). Good build quality (made in Japan). Two Ross RE-377s in original case; take standard XLR mic cables and each needs a single AA battery. Good build quality (made in Japan); I used them for recording rather than live work. Anyone into home recording/sound engineering who could use them? Collect from top Amersham.
