Mainspring for 1857 Remington (Maynard Lock) .69 Smoothie

[Eggman]

Would like to replace with modern made. The original mainspring has a 3 3/4" business leaf, an anchor pin 3/8' up around the bend, and an anchor wedge 1 1/2" up to the northeast. Original is a beast. Email dutchpiper18@yahoo.com.

Part ordered. Please disregard.
