Linhof Spirit Level brand_Sirui It won't fit a Spotmatic-This is an original Linhof bubble level. It says "Linhof" on it, which is kind of cool, but note: some of the spirit has evaporated, so those bubble levels are not quite as precise as they were before. And there's an engraving ("LG") on the base of the hot shoe mount, where it won't affect function. Not perfect, but there you go. Includes box.
