Here's some of my favorite helmets and mice in my collection including a U-384, U-384B in blue, U-388, U-393, U-393A, U-394, U-395 and the broken one is an early Victor helmet from around 1905-06 according to Michael Spadafora. It has a really nice greenish tan glaze like you see on some early Fred Locke specimens. Maybe one day the other half will show up https://www.insulators.info/pictures/?op=original&id=574960166
