The specific model is not listed here, but sometimes models are very close so a different model manual may help. Differences between models sometimes are limited to the number of extra stitches or capabilities, ie a J276 may be very close.
The other possibility is the likelihood that the Wards machine was made by a regular sewing machine company and branded it with Wards name. If you can determine the manufacturer, you may be able to find a manual that way. A sewing machine repair shop might be able to help you.
