Hey y’all. I’ve recently found a WFL marching snare with a P-35 strainer on it. Everything about the snare is in great shape except the throw off handle will not stay in the upright position in order to keep the rot gut snare wires against the resonant head. I’m not well versed when it comes to this vintage of drums and really could use some help. I’ve tried scowering the net for replacements or even just ideas as to why it’s not working properly. Any help or advice would be greatly appreciated. Thanks in advance!
