Mamiya C330 Pro Medium Format Film Camera with 135mm Lens And Focusing Thing

1:4.5; 135mm FOR PARTS! I’ve no idea what that addition on top is, but it seems to be a magnification/ enhanced viewfinder feature—albeit not very well?🤷‍♂️ Regardless of how it’s alternated, the same red pointer can be seen inside. You can see that in two photos. Nothing the lenses were pointed at showed up like it normally would—at all.🤔 If you know how to take this extra doohickey off, and run it by me, I’d be able to check if the inner view of the actual camera is perfectly fine or not. The cocking mechanism works just fine—if you use your finger on the shutter part directly that’s on the lens. The press downable button to release the shutter seems jammed, in comparison. The lenses are mega dusty, as you can see. Look at all those specks! This is what happens when it isn’t touched for over a decade, despite being wrapped in multiple plastic bags! Oh, the lens cap is very loose and has a chunk of it missing—but it’s not like you’ll be taking photos with that, by itself!!🤣 Being sold as-is! Please fix it up real nice!
