Santiago, the MU's are brass I'm pretty sure because I've straightened them since the photos and they bend easily like brass.
Erik, good point. Do you happen to know if ALL Grande F7's had anti-glare paint? And if maybe they were delivered w/o anti-glare paint and were in service for a while w/o before the Burnham Shops applied it? No big deal, but interesting.
Scott, and others. Thanks.
Bill
