Just picked up this Vintage machine complete with manual that happens to be missing pages 11& 12. Any ideas how I can get those 2 pages?

You may be able to get those pages by joining one of the Yahoo groups that specialize in Kenmore machines. They often have copies of manuals in their files. Go to https://groups.yahoo.com and search for Kenmore Sewing machines.

The other option would be to buy the whole manual. Just do a search for Kenmore Tri-Span 88 manual. Usually, multiple sources show up.
