As I get older, I find I am more interested in things from the past.  Among the 
gadgets that I have squirreled away is a landscape lens for a dry plate camera, 
manufactured around 1890.  The lens is a Ross London No. 6 Symmetrical 8-inch 
focal length, to cover 5x7 inches, and it is equipped with rotary Waterhouse 
stops from f/16 to f/64.

I am in the process of fitting the lens to a M42-mount lens board to permit its 
use on a Pentax bellows unit attached to my Olympus E-1 DSLR.  For a dry run, 
to be sure that I had the dimensions correct, I assembled the parts in a 
temporary manner to take a few test shots.  All shots were hand-held; I'm sure 
that the use of a tripod would improve things.

The lens itself.  A similar lens is shown under Ross on the Camerapedia.org 
website:

A black and white image to look at sharpness and contrast:

1890 meets 2010;  a contrail with a faint view of the passing jet:

I will find some period subjects when I get the project completed.
