I have an early Seth Thomas 124 movement (has the early version of the auto-correct lever). With the removable front lower panel, am I able to replace a mainspring without taking the entire movement apart? That is what the removable panel is designed for - correct? Thanks!

Yes, be sure to watch for, and keep up with, the spacers when you take the half plate off.

If I remember correctly this movement is the one that has 2 ratchet wheel gears per mainspring along with 2 clicks causing you to wind counter clockwise. This movement is the one where the chime mainspring is so powerful that it's been known to pull the rivet right out of the barrel. I had gotten a tambour clock with this movement in it. The 2nd wheel on the time train was completely sheared off where the arbor meets the pivot. Luckily I had a gear that worked but had a wider pivot diameter so I needed to widen the bushing a bit. The clock ran flawlessly after that but I've since let it run down once I heard about the mainspring issues

Dickstorer you are correct. The movement I am thinking of is 113 which is the big brother. I always get 113 and 124 mixed up
