Status
No longer offered; Gruppo Gamma's own Peacemaker Bronze lineup (gruppogamma.com/products.json, 38 SKUs, checked 2026-09-12) lists only PN-07, PN-08 and PN-19, all green fume dials; no PN-20 handle or SKU exists on the maker's own store. The record's only maker citation had already pointed at PN-19's product page rather than a page for PN-20 itself, a capture error rather than evidence PN-20 ever had its own maker listing.
