2 Vintage O'leary Trumpet Or Coronet Music Holder Mounts+2 Others-Estate Find

Hi all. Have 4 Vintage Trumpet or Coronet Music Holders to offer. One is not pictured and will throw that in the mix. They are-2 O'Leary. One with 3 rings and the other with 6 rings (one ring is broken), 1 unknown maker with 6 rings, and an old Duplex silver plate dated Sept 8, 1903 with a broken latch but workable. All have the the screws and holders. From a recent estate. Thanks and good luck.
