Metal or transparent plate to cover bobbin

I would just like to say a huge thank you for such a quick and fantastic service. The sewing machine arrived today which was amazing considering I only placed the order a couple of days ago and live in Jersey. I would also like to thank you for including some accessories which was a real surprise. Although the cover wasn't the right one this more than made up for it. I will be highly recommending you to anyone I know thinking about purchasing a sewing machine. Customer service like this is incredibly rare these days. Thanks again from an extremely happy customer.
