This is all very surprising, I must say.
Now, what's this about little antennas around the bridge? Sticking out in which direction?
They are more like elongated bulbs on both port and starboard sides of the series production bridge.
Here is a pic of the 11 footer prior to its 1991 restoration. Note the little red thingy on the lower side of the bridge dome.
There's one on the other side as well. They look like they could be lights but there's no indication they were ever lighted.
