As we're still on this subject, I thought I would post photos of this nearly mint B-Type. The colour of the chamois is a cream shade, not furry and not at all yellow as in the B-Type at the top of this thread.
I reckon if an attempt was made to clean this chamois to remove the small amount of grime - no doubt it could be brought back to brand new "clean" condition. After treatment I doubt the chammy would look anything like the B-Type in question. I still lean towards it being re-lined. With an amount of time, original stitch holes could be used, in my opinion.
