Came in today. No oil whatsoever. Evidence of wire edges having been ripped off something fine. Porous but purges quickly after wiping off. Stupidly hard. It took a good while with sic wet dry to generate that pittance of slurry. Going to be a bad one to lap. 732.7g. 20cm x 5.1cm x 2.9cm. Will post more when I clean the thing up.
