Wolly Raptar series IA coverage?

[athanasius80]

Hey guys,
I just acquired a Wollensak Raptar series IA. Its f6.8 with focal lengths of 6 1/2, 10, and 12 3/4 inches. Does anyone have experience or an estimated guess if this guy would cover 5x7 without vignetting?
Thanks!

According to the cat. listings from Seth at Camera Eccentric, the 1a is a 3.25 x 4.25 lens, though the aperture for that lens is listed as 6.3, not 6.8 - and the focal length is 5 1/8. The one listed as 6.5" is the 2b, for 4 x 5.

The earlier Velostigmat is 6.8, but the Velo 1a is 3.25 x 4.25 as well. That said, I believe the front cell reversed and set behind the shutter would certainly cover 5x7.
