It's unfortunate that the Yahoo Collector's site is making changes and is not very responsive these days. Most of the info you seek could be found there. You could also search the other 1911 sites. Plenty can be found on those too. A simple way to avoid "cut and weld" frames, slides, and barrels, and be relatively sure of a good specimen would be to look at prefixes rather than serial numbers. D, C, and CR prefixes would be preferable on Seattle/Bellevue CM's. Keep in mind that some shoddy assemblies got out of Seattle as well as GA, even within the prefixes given. However, as long as no "gunsmith" did any butchering to the guns, they can usually be put in good working order by a smith who knows what to do. The odds are actually in favor of the Georgia guns when it comes to correction of assembly problems, simply because of the quality and dimensions of the parts that were used in production.
