Wista 45SP Back Door

Hi can the back door on the rear standard of the Wista 45SP be detached, I.e. leaving the ground glass?

Thank you

Are you talking about the focus hood assembly?
Open the folded assembly towards the left, apply an upward pressure along the hinge axis, then lift the bottom towards you. This should disengage the pins and let the top of the hinge/pin assembly drop down. Whole hood assembly should be free in your hand.
Butkus has the SP manual if needed.

The focus hood assembly is part of the door.

Thank you
