AI MK IV Radar Aerial

Hi, Does anyone on the forum have any detailed shots of the Mk IV AI radar aerial used on early Beaufighters and other Night Figthers? Trying to ID some parts that look like they could be from the AI Aerial found at a Beau crash site recently.

For those who haven’t seen one of these the early MkIF’s and later marks had what looks like a “cupids bow” on the very front of the nose.

Thanks and fingers crossed some out there has the info.
