Hello Doreen,
Very difficult to get hold of books for Crofton for some reason, if it is at all possible, e-mail a photo of the front of your model and I will try and match another make and model, remember that most "Sundry" machines as they are known are made by one manufacturer and different names out on so you may be lucky, hope I can help you.
