I reread your questions and didn’t notice you asked if both sides of the grip were embossed with Webley. I looked at the pics again I am really surprised I never noticed only one side has Webley embossing. I looked at those pics over and over looking for each little variation, missed a pretty obvious one. lol. Talk about a transitional gun, lol
Were they using up the last of the prewar grips as well as the triggers?
