Unlike the M67 there is a wide variety of "Lemon" Grenades. The first grenade nicknamed "lemon" was the M26 adopted in the 1950s. Later US envolvement in the Vietnam war resulted in many improvements being made. The: M26A1, M26A2, M33, M56, and the M61, are all variations of the iconic Lemon grenade. There were also production variations that did not have seperate "M" designations.
The GM26A1-V is an exacting replica of the M26A1. It has the classic lemon shape, 9/16" threaded fuze hole, a M204A1 Fuze Head, with a curved spoon and the markings are from a 1965 production lot.
The quality you've come to expect from RMI reproductions can bee seen in these. The body is formed steel, NOT CAST IRON, exterior finish is an olive drab powder coat, and the markings are period correct. Fuze head is an actual M204 surplus fuze (those were hard to find!) that has been refurbished.
