VTG I ROWi I STG I Cancer Lobster Crawfish Pendant

A vintage sterling silver pendant by ROWi, aka Rodi & Wienenberger (ROWi being a combination of those names), a German company founded in 1885. The ROWi trademark was first used in 1973 & registered in 1975, so this charm would date between the mid-1970s to the mid-1990s (when it was acquired). The charm depicts the Lobster, or Crawfish for the zodiac sign Cancer (usually a crab). Hallmark shown in photo 3 (925 indicating sterling), measurements in photos 4-5. Photos show angles & condition.
