I was looking at this horn on Tenormadness, and it has this description :
"Beautiful example of horn from this vintage (early 60's). Still has the old style side Bb and C keys. It has been repadded not by us, but done very well..........................etc"
what is "old style side Bb and C keys" ? How different they are, comparing with "new style side Bb and C keys" :shock:
Here is the photo from tenormadness:
