Model 21 was available in several different styles and configurations:
1. Standard Grade: chambered in 12-, 16-, 20-gauge; barrel lengths 26", 28", 30", 32"; matted or ventilated rib; select walnut checkered pistol-/straight-grip stock; checkered beavertail fore-end. Built from 1931 to 1959.
2. Tournament Grade: same as above; special dimension stock; marked "TOURNAMENT" on bottom of trigger plate. Built from 1933 to 1934.
3. Trap Grade: same as above; slightly better-grade wood; stock made to customers’ dimensions; marked "TRAP" on trigger plate. Built from 1932 to 1959.
4. Skeet Grade: same as above; addition of 28-gauge; stock furnished with checkered butt; marked "SKEET" on trigger plate. Built from 1936 to 1959.
5. Duck Gun: chambered for 12-gauge; 3" Magnum shells; 30" or 32" barrels; Standard Grade stock, except for shorter length of pull; marked "DUCK" on trigger plate. Built from 1940 to 1952.
6. Magnum Gun: chambered for 12- or 20-gauge; 3" Magnum shells; same stock as Duck Gun; not marked on trigger plate. Built from 1953 to 1959.
7. Custom Built/Deluxe Grade: chambered for 12-, 16-, 20-, 28-gauge and .410 bore; barrel lengths from 26" to 32"; stock built to customers specifications using fancy walnut; marked "CUS­TOM BUILT" on top of rib or "DELUXE" on trigger plate; these grades are frequently, but not always engraved. Built from 1933 to 1959.

NOTE: Some early Model 21s furnished with double trig­gers, extractors and splinter fore-ends. This combination reduces price of the gun regardless of grade. Deduct about 25 per­cent.

NOTE: Add 30 percent for 20-gauge Magnum. Factory ventilated ribs command a premium of about $1,800 on 12-gauge; $2,500 on 16- and 20-gauge. Model 21s with factory furnished extra barrels will bring an additional premium of about $2,500. Refinished and restored Model 21s are in a somewhat unique category of American-made collectible shotguns. A gun that has been professionally refinished by a master craftsman will bring approximately 90 percent value of factory original guns.

Prices paid for guns of this grade are determined by gauge, barrel and choke combinations, rib type, stock specifications and engraving. Expert appraisal is recommended. It is best to secure a factory letter from Cody Firearms Museum. With respect to such a letter, it is important to note that these records are incomplete and may be inaccurate in a few cases. Records for Model 21s built during 1930s may be missing. Special-order guns may have incomplete records. In such cases, a written appraisal from an authoritative collector or dealer may be helpful.

When Winchester moved production of Model 21 into the Custom Shop, a number of styles were greatly reduced.

There were now three distinct styles:
1. Custom Grade: chambered in 12-, 16-, 20-, 28-gauge and .410 bore; barrel lengths 26" to 32"; matted rib; fancy walnut checkered pistol-/straight-grip stock; checkered fore-end; pistol-grip guns furnished with steel grip cap; a small amount of scroll engraving was provided on frame of this grade.
2. Pigeon Grade: same chambers and barrel lengths as above; choice of matted or ventilated rib; leather-covered recoil pad; style "A" carving on stock and fore-end; gold engraved pistol-grip cap; frame engraved with 21-6 engraving pattern.
3. Grand American Grade: same chambers and barrel lengths as Pigeon Grade; addition of "B" carving on stock and fore-end; 21-6 engraving with gold inlays; extra set of interchangeable barrels with extra fore-end; all enclosed in a leather trunk case.

EDITOR'S COMMENT: According to Ned Schwing's excellent book, "Winchester's Finest, The Model 21", there were only eight 28-gauge and five .410 bore models made during the Custom Shop production era from 1960 to 1981. Any price estimates would be highly speculative.

NOTE: Add $4,000 for 16-gauge; $5,000 for 20-gauge.

NOTE: Add $6,000 for 16-gauge; $5,000 for 20-gauge.

NOTE: Add $15,000 for 16-gauge (extremely rare); $5,000 for 20-gauge.
