Hi John, looks like haven't removed all of the horn pad assembly yet - 4 screws around the horn contacts. I recall them being phillips head on mine maybe allen key on yours?

This is what it should like like with it removed - you can see the 4 smaller inset threaded holes for the horn assembly and 2 larger ones at 12 o'clock and 6 o'clock positions that you can use for a steering puller. Cheers
