Alexander - Slide Locks

I tried ordering some of these from another source but they have been on back-order for most of a year. I ordered three of these from Pope along with a preowned horn last week. The locks didn't make it into the package for the horn shipment, but when I informed Pope instruments about this the locks were shipped to me right away. I'm using these on an E. Schmidt Kompakt double; I believe the horn's tubing wall thickness is slightly less than a typical Alex and the ring would not close enough to grip the slide right out of the bag. I had to "massage" the lock ring with a small amount of filing so it will close a little more and snug onto the tuning slide...now it works perfectly and looks absolutely gorgeous. Thanks so much to Pope Instruments for having these items in stock and correcting the oversight in shipping in such short order. 5 Stars 'cause that's the most I can give.
