[LargeFormat] Kodak 7 1/2" Ektar Coverage?

[Les Newcomer]

The only 190 I show in my 1954 booklet is the Wide Field Ektar. 
Kodak says it covers 8x10 without swings and has an angle of view of 56°x68°*
*At maxiumum aperture, for larest recommended neg size, no swings. 
(I've never been able to define their use of "maximum" here, wide open
or stopped down?)

filter size is 63mm or Series VIII. These should drop in the front and
held in with a series VIII shade or filter ring, no press-on adapter needed.

From the 40s through the early 60s, the date of manufacture can be
decoded by using the two letter part of the serial and the following rule


C A M E R O S I T Y
1 2 3 4 5 6 7 8 9 0

 Thus an RO serial number was made in '56

I use mine on my 8x10 with great results. Best to use it at f16 or greater.
