Great solid tables
I have a friend that worked for SW for over 10 years. True SW tables are very good solid tables, many designed similar to Brunswick. Installed properly by a good table mechanic, they will play as good as their Brunswick counterparts.
Complaints about cloth, bucket sizes, and even the silly pocket covers are all addressable by a good mechanic.
Some caveats, just because it has a SW nameplate doesn't mean SW made it. Common practice had service techs switch name plates from the original manufacturer, many are really Brunswick. I have three antique Brunswick 9 tables. One a Brunswick Madison, almost the twin of this table in question. Almost, but not quite. The other two have SW nameplates (restoration in progress) but are truly Brunswick. My confirmation is the patent stickers, all Brunswick patents.
In any case, great table for the price. If you want more info, provide more pics of any nameplates, stickers, patent into, and underside numbering of the wood. Bolt heads too for the rails. Only Brunswick used a certain head and thread pattern.
My guess without further info and pics is that this is a SW table.
Good luck!
