7/8" _is_ 22.2mm, so that may not be what you're looking for. According to Sheldon Brown's site a 22mm stem would be French.

My Sutherland's 3rd Edition has this:

22.2mm (7/8") England, Belgium, Italy, Japan 22mm Germany, Austria, Denmark, Switzerland 21.9mm France, Spain 21.15mm (.833") Japan (on many bicycles for U.S. market)

Check your steerer tube on the fork. Maybe there's rust or burrs that make it look like it's 22mm and it just needs cleaning up with some emery cloth wrapped around a dowel. A 22.2mm stem may fit after all.

BTW, you can buy decent inck/metric digital calipers these days for very little money. Canadian Tire has them for $35 and they routinely go on sale for half price.
