Just got a Corder snare that arrived from Ebay today.
Was going at a bargain price because the snare tension knob was stuck in the snare attachment plate due to cross threading.
A few minutes with channel lock pliers and a vice and voila,no more stuck.
Probably needs to be rethreaded and tapped ,but the hardware is immaculate.
No rust ,dents or pitting on any of the chrome.
Will post pic's and vid when ready.
