This collection of screws is from a now closed brass instrument repair shop. It contains many samples of the Allied screws such as lyre holder screws (A440, 441, 442, 443, 1690), wing screws (A444, 445, 446, 448, 449, 1691,), and tuba bell screws (A212). There are also several different kinds of stop arms and stop arm screws; and stop plates and stop plate screws. You can also get a good idea of the contents from the picture that includes the upper lid of the box. The Allied screws alone are worth c. At Allied’s present prices. The stop arms etc. Would add to that.
