Hello. I'm a new member, and just acquired a Kundo 400 day clock, non-running, from a junk shop. I replaced the mangled suspension spring, set the beat, and it's running pretty well now. But I have a couple of questions. My clock movement is plate no. 1367 from the repair guide, and has a bottom locking guard that looks like the one shown in appendix 123 - Kundo standard 49. However, the bottom block of the suspension unit is a Unit 3A-Kundo standard 53. My first question is, what is the purpose of this bottom locking guard? I can lower it down over the bottom block so that it prevents rotation or swinging of the pendulum, but it provides no support. If I move the pendulum out of it's cup and out of the way, I can fully lower the locking guard, then with some difficulty and much trepidation, I can hang the pendulum by the bottom block resting in the lowered locking guard. But this puts a lot of slack in the suspension spring, and is accomplished with great risk of kinking the spring at the bottom guard. I realize part of the problem is that my 3A bottom block is probably not the intended block for this style locking guard, but I still don't understand the purpose of the thing. Instructions from the early 50s only mention it in reference to lifting it out of the way prior to hanging the pendulum onto the block. My second question concerns the click spring. My spring does not engage the click at all. I have to manually manipulate the click when winding. Can this spring be safely bent back into shape? Thanks!
