Here's a couple pics of the S-41's I was given.I wonder if that Philips tweeter might be a replacement - most Scotts of this era used cone tweeters, and I think I might see in the upper right signs that there once was a screw hole - there appears to be a little ridge like those made by screws peaking out from behind the foam gasket.
I could be mistaken, since I seem to remember the Scott Pro series - I had the 70s - used the Philips dome. And mistaken or not, the dome might be considered by many listeners to be an improvement.
