please help
A non-profit organization where I do volunteer work as been gifted with a heavy duty sewing machine. It says Union Special, and the number on it is 63400B. It is missing the bobbin cover plate and manual. The operations manager searched on line for a manual and cannot find one. Today the needle broke, and she found a universal needle does not work as a replacement. The shop works strictly with donated items and recycles them to make rugs, bags, placemats, etc. There is little/no money for extras. The machine was sewing well before the needle broke.
Also, it does not appear to have a reverse setting, at least we can't find it.
Any suggestions or information will be much appreciated. Thank You!
