Thank you all for your comments, now today is supposed to be a sunny day - we shall see, if it is then I will get the machine into better light to examine it more clearly. I did not do anything to prepare the machine for the photos, the condition you see is how it arrived which was so unexpected and of course I am delighted. Now I did not know what a potted motor was and had to go looking on the internet and also at the back of the machine, so again thank you for that information. As it is in a smallish cupboard I am hoping that once I can get this into daylight that I can get the treadle belt in place and then perhaps have a little go at treadling - oh such a long time since I was able to do that.
There is a box of feet etc. and strangely enough in it is a foot that someone else was asking what is was for the other week - an adjustable hemmer, there is also a binder foot, a gatherer, a darning foot with a very small hole, two roll hemmer feet, a quilting foot with its guide, an under braider and its fixing screw, an edge stitcher and an odd looking bobbin case - the like I have never seen before, plastic bobbins and only one metal bobbin, screwdrivers. The darning foot I have is nothing like anything I have seen before but has a spring at the top - so above where it fits onto the machine - in fact all the feet are in excellent condition no sign of rust whatsoever which is good. Once I am more together today I will try and get these laid out and take another photo and see if I can upload it again.
I already have a couple of rufflers from a long time ago, and one or two other feet that I kept, there is no zipper foot though, but I am sure this can easily be remedied.
