   This is almost certainly a Turner-Reich triple 
convertible. They are not among the most valuable lenses 
because their performance is often not very good. Partly its 
the design, Ernst Gundlach's attempt to get around the Zeiss 
convertible Protar patents, and partly because its a hard 
lens to make. I'm not sure of the 18" version but the 12" 
was made in quantity for the airforce for a general purpose 
8x10 lens. Now, the problem is that a replacement lens of 
another type will probably be more expensive than a T-R if 
one can be found. At a guess a fair price for a T-R in good 
condition would be around $300 but I am not an expert on 
value.
   Perhaps some old auction prices can be found on e-bay.
