Havey Smith did a nice 4 page article on the restoration of horns from the late 356 and early 911. I took mine apart and they were like new inside, so a cosmetic makeover was the only thing I had to do. The horns had beed sitting for 20+ years so I didn't expect them to work before I took them apart. When I was all done........nothing, not even a grunt! Has any one had experianced the insides of one of these early horns?
