Brass cowl vent

Exceptionally heavy and thick-walled vent, made in a small casting workshop in northern Italy.
Traditional nautical piece in a round or oval design with matte-polished finish.
The sand-casting process by hand creates a finish that, with the production structure, leaves no visible holes, dents, or cavities.
Included is a round deck flange (diameter = D3) onto which the vent can be screwed and which can be mounted with three strong knurled thumb screws.

A vent that can outlive many a ship!
