Yoke Spring, Pendant Set Part #1229 Waltham 18s - Model 1883 - Fun in the Sun
After sorting through some movements to sell as "steampunk", I noticed one that had a part to fix a movement I stuck away somewhere months ago. Ah - I remember - a 18s Waltham that would not wind.

After removing the balance, barrel, and top plate, you can clearly see the bad guy

Not sure if it is common for the "Yoke Spring" to break or not. It is the 1st one I have ever ran across INOP (no expert - just an old rusty Warrant Officer)
