Dear Ariel owners,

I removed the ventilation cowl on the deck of my 1965 Ariel #330 near the bow. The original installation appears to have been an aluminum deck ring with screw-in cowl, and perhaps also a screw-in deck plate. A previous owner cut the vertical section of the deck ring on a Nicro three-inch cowl and screwed it on top of the original fitting. I removed everything and cleaned up the original deck ring, but cannot determine manufacturer.

The manufacturer's name did appear on this ring at one time in a small oval mark, but it is almost worn off and it currently looks like the letters "NEBIUIU" or "VARIUIU" but neither of those names sounds like anything I have heard of. I also don't know if this ring was the original installation.

The deck cut out is precisely four and one eighth inches. All of the catalogs that I have consulted require either smaller or larger cut outs for their ventilation cowls. I would like to install a new screw-in style cowl vent with ring, or find a new screw-in cowl and deck plate for the ring that I have.

Does anyone know a source for this item? Cutting a larger hole in the deck is certainly possible, but I consider it a last resort.

Thanks,
