It's not an Ortho film, the word Chrome was added to show it had a wider Chromatic response, still not fully panchchromatic though.

Verichrome dates back to around 1908/9 when it was released by Wratten & Wainwright, and the term was in constant use for B&W films until the demise of Kodak Verichrome PAn.

I'd sugeest see-sawing it in a tray with D&^/ID-11, it's an easy technique when you don't have a tank that takes the film size.
