Brass 425 Self-Propelled Air Defense System — Micro-Scale Military Miniature for Diorama and Display

Modern warfare isn’t won by tanks alone — and this micro-scale miniature makes that point quietly.

The 425 tracked self-propelled gun-missile integrated air defense system is a distinctly contemporary piece of military hardware: radar-equipped, multi-role, and designed to operate on the move. At 21.5mm long and just 8 grams, this brass casting captures its angular, purposeful silhouette with a level of detail that rewards close inspection.

For diorama builders recreating modern battlefield or near-future military scenes, it fills a role that most miniature ranges overlook. Position it alongside infantry, AFVs, or other armour — or let it stand alone as a conversation piece on a desk or shelf.

Paint-your-own hobbyists will find it takes primer and weathering well. Collectors who prefer it raw will appreciate the warm brass tone against darker base materials.

Caring for Your Brass

Brass develops a natural patina over time — a sign of age and character, not damage. To keep the original shine, wipe occasionally with a soft dry cloth. For a deeper clean, a small amount of brass polish or a paste of lemon juice and baking soda works well. Avoid prolonged moisture or harsh chemicals. The more it’s handled, the warmer its glow becomes.

A small amount of blu-tack or double-sided tape can help it sit perfectly on your shelf.

Each piece is individually cast, so minor variations may occur.
