I'm setting up my Durst L184 and would be interested in buying a scrap 8x10 negative. This would help me in setting up the enlarger (i.e., check for lens coverage, etc.). I have lots of 4x5 negatives but have not bought an 8x10 camera yet. Any negative, improperly exposed and or developed would be OK, as long as it has some image on it. Thanks.
