Question For RFA Collectors: Blackened 1916 GM Economy

[SemperFi]

I recently added the attached blackened RFA 1916 GM badge to my collection. It’s a legit badge, but its blackening made me curious.

I’m assuming the badge was either blackened on the initiative of its owner or under battery directive, but am reaching out to the Forum’s arty subject matter experts to learn if were there any British RFA batteries, or higher formations, that wore blackened badges during that timeframe?

In other words, were there specific RFA units that wore blackened badges akin to blackened badges worn by some TF infantry units?

Thanks for your help!
