Ginger

Ginger (Gun), 2018 edition, was the 50th tier of the Lumber Yard in the Christmas Event 2018, and each tier of the Lumber Yard cost 1 Log according to the curated data. The event page says the Lumber Yard had 100 tiers, so tier 50 sat halfway along the track. The event ended, and trading is now the only route.

Not the 2015 gun

The wiki warns that this is not Ginger Gun (2015), a different gun from the Christmas Event 2015. The year in the page title is how the two are told apart, so use it when searching.

A gingerbread revolver

The base has a gingerbread texture, hence the name. Along the top of the revolver sits a thick coating of white frosting. The cylinder and hammer are red, while the front sight and trigger are green. The handle carries a green bowtie, two red buttons and one green button.

Origin of the art

The wiki lists the decal as published by didi1147 on December 18, 2018. Its partner is Ginger Knife (2018), which came from a box rather than from the Lumber Yard, so the pair were sold in two different ways.
