Ship propeller - Bronze

This is a three-blade ship propeller, made of bronze or gunmetal (a copper-tin-zinc alloy). The dark patina and wear indicate considerable age. As an antique/vintage maritime piece, it has collectible value.

- Visible: "LH" = Left Hand (left-handed propeller, rotates counterclockwise)
- Possibly also a size number above
- Text runs around the hub
- On the right: something that looks like "MM.31" or a diameter/spin/pitch indication
- The construction and marking style point to European origin, probably
- British, Dutch, or Belgian — given the "LH" marking in English and the construction style
- Likely early-to-mid 20th century (1920s–1960s)

Note: The initials of the inspector or foundryman who checked the propeller during production — this was a common practice for ship propellers from the 1920s–1940s
Or a quality or batch mark of the foundry
