I have three Visual Fields machines that a collector may be interested in:

A/O Bromberg Visual Field Instrument circa 1920,s

A/O Stereo Lloyd Campimeter circa 20's 30's

Davidson-Wottring Caecanometer circa 50's

These are in excellent condition and have
original instruction books and recording charts.

e-mail me at jetod@rushmore.com if interested. I can e-mail pictures also.
