Plaubel Peco 8x10" bellows - tight inner dimensions?

[darkroom_rookie]

A question for the owners of Plaubel Peco (Profia?) 8x10" cameras. What are the inner dimensions of the bellows frame? On the bellows I have, the dimensions are 246 x 246 mm (see attached pictures). Could this cause mechanical vignetting on the longer side of 8x10" format if using a lot of shift?

i have just checked mine, same numbers.
the camera is european and therefore made to european standard 18x24 cm.
that is only a few mm shorter than the 8x10 inch (but app 20 mm narrower).
i see no reason of any problems in shifting. (havent checked though)

Klaus, thank you for your answer. Seems there should hardly be any problems. Since these are actually to be attached to a Sinar P 8x10" standard frame, I've gone the route of making my own Sinar bellows frames to be epoxied to the Plaubel bellows. Finding cheap Sinar 8x10" Norma/P bellows without pinholes is a near-impossible task!
