I have also just purchased a Busch 4"X5"
also from http://www.ebay.com probably from same
seller that sold to Doc{Emanuele in Beverly
Hills} and it appears to be in excellent shape
I purchased a MFG's Manual from John Craig
He sells Manuals on most every Camera Mfg'd
at a reasonable price. His address on the net
http://craigcamera - A worthwhile look. He also has manuals on rangfinders and lenses.
