Minolta maxxum HT si yellow viewfinder

My cousin is into photography as well and has a Minolta

maxxum HT si I noticed it's very yellow through the

viewfinder. This camera was bought new by his dad in

the 80's. Is this the focusing screen being stained? And

can it be fixed?

<p>If it is on the screen, I can't see how it would be possible to remove the staining. Certainly not worth getting it fixed, as they are worth very little.</p>

<p>A long shot - could it be the lens? If so it shouldn't be visible with the lens removed.</p>

<p>An even longer shot - could there be a light yellow filter on the lens?</p>

<p>If the focusing screen is clean and clear it's in the viewfinder. I've seen old rangefinders with yellowing viewfinders.</p>

It's not the lens I'm sure of that, it's either the viewfinder

or focusing screen which I'd only describe the yellowing

as looking like glass in a heavy smokers house. However

they are not smokers and never have been. His dad

bought it in the 80's so it's got sentimental value. He's

been using it for years like that with no problems but

when I look through it I'm amazed he can even get his

pictures in focus. I imagine that it wouldn't be too

difficult to fix but as I don't have the camera in hand I

can't really get a look at it
