Except for those places near the bobbin, this one looks like it had very little use. I wonder why there is so much grime there? The 185 is a great little machine. Apparently those plastic cases are not super durable, so finding one with the original case intact is a plus. Mine had a lot of scuff marks on (the case) and I was able to get most of them off by scrubbing. Good luck bidding.
