I had another look at the enlarger i mentioned in my previous posts, and it seems its not that the filter drawer itself is bent, but that the piece of plastic or something has come off the front? The drawer itself is there, but not the bit at the front that stops it from going right inside the enlarger and getting stuck, and stops light from leaking out the front. If that makes sense. Can anyone think of any way i could rig up a solution for this?
