We are in possession of hundreds (thousands?) of what seem to be glass
slides. The glass is 3-1/4 x 4, the image area is about 1-3/4 x 2-7/8. The
images are very sharp and detailed, largely architectural but many other
topics besides. What are these called? Has anyone had any success shooting
regular slides from these? Or any info on a projector? Any help would be
appreciated.
 
Thank you.
