The listing is for one NOS mainspring only, your choice. These are almost all for vintage Elgin watches. The numbered C. & E. Marshall Co./ Marco envelopes are not included as I have more mainsprings and will reusing them. Free shipping within USA, International shipping is only through the eBay Global shipping, please estimate this before making a purchase.
Look at the pictures for more information about each mainspring. I have more than a thousand mainsprings that I will be listing as time allows.
