This Linhof 4x5/9x12 right angle viewfinder is in excellent condition overall. This is the desirable later version two piece finder which allows the user to change from landscape to portrait orientation and back again. Horizontal and vertical viewing with the 2pc capability Linhof refers to this as the "Corner Mirror 9x12/4x5" 

Mounting well. Clean overall. 

Very useful and a pleasure to have and enjoy!
