bases have legs in the mission style, and the tops are heavy and squared, also with wood or metal bands. The "Colonial" and "Art Mission" styles share the same book sections, but the tags may read "Colonial" or "Art Mission". The top and bottom are what distinguishes these styles predominantly. Generally available in Quartered Oak, Genuine Mahogany, and Genuine Walnut. Available in "single door" and "double door" configuration as well. The difference between "Mission" and "Art Mission" is the bands. The Mission series having metal bands and metal knobs.
3. Colonial Style: Also the "300" series (308, 310, 312, 340, 349, etc...) - See the Art Mission description above. The main difference is the front of the top and base sections has a rounded appearance and the legs are rounded in front as well, in the typical colonial style. These seem to be more rare, and I have not seen any in the metal band configuration, unlike the mission series. The tops to these weigh a lot! They are very heavy and solid. Generally available in Quartered Oak, Genuine Mahogany, and Genuine Walnut. These are also available in "single door" and "double door" configurations.
4. Standard Style: The "100" series, and the "Standard D" and "Standard C" series (108, 110, 112, 143, D-12 1/4, C-9, etc...) - This is the most common series seen and sold here on e-Bay. About 34" wide. Comes standardly in the "D" depth or about 11 1/2" deep or the "C" depth or about 9 1/2" deep. Also comes in a deeper "E" section about 13" deep and then the custom, and very rare "G" and "H" sections. The standard top as well as the standard base for these has been called by many names; Rolltop, Waterfall, Ogee, Rounded front. These have metal bands, mostly brass, some copper as well. Metal knobs, mostly brass, but some copper as well. Generally available in Plain Oak, Quartered Oak, Genuine Mahogany, and Imitation Mahogany. Available in "single door" and "short" configurations in both the "D" and "C" sizes.
5. Sheraton Style: The "500" series (508, 510, 512, 541, etc...) - This is a fancier style with inlays on the faces and the sides. These are, like the Universal style cases, VENEERED sides. These were manufactured only in real mahogany, as far as I know, and are pretty scarce. I believe these are meant to be the Cadillac universal style, so the tops are square and the bases have legs, but not in the mission style. Generally available only in Genuine Mahogany. Available in "single door" and "double door" configurations.
6. Ideal Style: The "400" series (408, 410, 412, 460, 440, 446, etc...) - This is the very fancy set from GW, the "Top of the Line" series. Panelled sides, very detailed trim, richly carved fronts. Solid wood for the most part. These do not have regular glass, but only bevelled or leaded glass. So, if you are buying one of these sections and there is regular glass, know
