Unknown Siren What could it be

[Robert Gift]

Thanks Archon.

But I liked your bigger pictures - if you can stack them beneath each other.

What a fascinating sound - a major 6th.
Never would I have expected that as a siren.

The shroud on the 6/10 siren I have is home made so don't get it confused with the horman in Long Island new york.
