Okay, so I made a big boo boo last night and broke my sear (don't ask, it involves my daughter and a vise). I bought my lock as a kit from Tip Curtis, so not exactly sure who made the lock (it's a left hand, large Siler). Anyway, are all Siler parts interchangeable? I see parts for Chambers Siler locks, but I'm not sure if this will fit my tumbler, etc...I'd like to order the part very soon so any quick help would be appreciated:) thanks!
