Scooped up a free Montgomery Ward Model 30 Sewing Machine with cabinet. Looking for instruction manual for it. Will have to swap out from knee operation to foot peddle due to aged electrical wiring. This cuties serial #W94889. Also underneath under paint is RBR 2 W. Any info on this keeper would be helpful. Thank you.

This is a branded machine made my National Sewing Machine company.
Here is a copy of the manual on this page which has a lot of info for you.
