Senglea Thanks Howard, good point and good research! Updated accordingly.

Senglea Thanks Jack - I've been seeing others post lighthouses here so I hope this is actually ok. I could only choose "ships" or "planes" as categories so I'm not sure if this actually belongs here? Any help for a newbee?

Senglea Many thanks!!

Senglea Cheers, that’s exactly what I wanted! :-D
