5x7 Gundlach Korona Iv

I've been attempting to find information about a 5X7 GUNDLACH KORONA IV. The period literature jumps from the series IIII to the series VI cameras??? Can anyone point me to information about the camera?

Thanks,

Of course that should have been series III to VI.

Not listed on http://www.piercevaubel.com/cam/gund.htm ?

hmm the 1900 catalogue (http://www.cameraeccentric.com/html/info/korona_1.html) does indeed not list a IV) and by 1910/20 the series designation has fallen out of the catalogue completeley (http://www.cameraeccentric.com/html/info/korona_2.html)

try

Thank you, Ken and Brian for the leads. I LOVE the prices in the catalog.
