Finder glass looks good. Even though I see some tiny cracks on the front of the finder. It seems that only one glass coating or layer is cracked. Damage is not visible when you view image from the rear. But I see some dust particles inside, they are noticeable, but  you still can frame the picture OK. If you look at the last 6 frames, you can see damaged front glass. It is hard to say if those are cracks or maybe glass separation. Since it is so small, I can't tell for sure. On second thought, it looks like a separation of the glass coating. 

Inside there are couple frames, two for 180mm lens and two for 85mm lens, with parallax correction for infinity. Over all finder is in average, to bellow average condition. It shows some wear on the exterior, metal parts have some scratches.  But it works good. 

Finder has low number Nr 6114, , on the bottom it  has Nr. 435/1. It was made before WWII. it is collectible item. 

Item is sold as pictured.
