I have a Blair Camera (Contained Field Version, I think) dated with
patient dates of 3/29/1887 and 5/20/1890.  The plates contained within
are dated with a patient of 5/15/1883.  The cloest I can find in
picture form are the Special Folding Hawk-Eye c. 1896 and The 400 c.
1895.  Both look to be much newer than the one I have.  Looking for a
record of my version with the prospect of trying to sell it.  Other
info contained on the camera is a lense # of 7433.  No model name or
number found on the camera.  It is contained in a leather covered
wooden box.  Front opens via spring loaded door which drops down and
the camera can then be rolled out onto the drop front.  Plates are
contained in the back with access thru a spring loaded pop up lid. 
Contains three plates.  Wood of the plates seems to be walnut and the
wood framing the camera itself is painted black.  Any into would be
helpfull.  Thank you.  Please use subject "Blair Camera," that way I
won't delete as spam.  I get too much of that.
