WINCHESTER MODEL 21-5 CUSTOM FLATSIDE 12 GAUGE 2 BARREL SET – SEARCH RESULTS AND ORDER SHEET AVAILABLE UPON REQUEST

A highly desirable late-production custom Model 21, this Winchester Model 21-5 Custom Flatside 12 Gauge Two-Barrel Set, completed in 1973, represents the peak of Winchester’s bespoke side-by-side work. Accompanied by factory search results and the original order sheet (available upon request), it offers both configuration depth and documented provenance.

The gun is fitted with two vent-rib barrel sets:
• 28" barrels marked IC and Mod (.005/.013) with 2¾" chambers
• 30" barrels marked Full and Full (.035/.038) with 3" chambers

Both sets are properly matched with correspondingly numbered beavertail forearms (marked 1 & 2)—a correct and desirable detail. Features include a single selective trigger, ejectors, steel-capped pistol grip, and a factory recoil pad, all executed in classic Model 21 fashion. The flatside action further enhances the clean, purposeful lines of the gun.

Condition is very good to excellent, showing light handling marks to the wood and metal consistent with careful storage and limited use. There are some signs of pitting near the top left receiver at the wood-to-metal junction; please reference photos for detail. Overall presentation remains strong and honest.

The gun weighs 7 lbs 13 oz with the 28" barrels and 7 lbs 15 oz with the 30" set, with dimensions of 2" DAH, 1 3/16" DAC, and a 14" LOP—a well-balanced, versatile Model 21 suitable for both field and heavier work.

A correct, documented Model 21-5 Custom Flatside two-barrel set—substantial, flexible, and increasingly hard to find in this configuration.
