Hi there, I'm new to the forum, so please be gentle with me, lol.
I have a UK hand held siren, shaped like a long funnel/cone, when you blow through the 'thin' end as a trumpet it lets out and incredibly loud siren. I think my uncle was in some sort of 'underground' Dad's Army and I'm pretty sure this is WWII.
Does anyone have any information about it, I've never seen one before?? :thup:
