<p>Thomas was asking about the MIRROR not the SCREEN !<br>
Anyhow, I'd be asking how the mirror broke. I've had OMs since 1974 and never had a broken mirror. The broken mirror might be the obvious sign of damage but there is a possibility that other parts of the mechanism are also damaged and maybe optically misaligned. If you really want a reliable OM-2N to use buy a good one, they sell for bargain prices these days.</p>
