Alloy Mainspring for LONGINES caliber 8LN, 8/68N

Unmarked Swiss Mainspring for LONGINES caliber 8LN and I believe 8/68N movements as perhaps other similar ébauche watches, white alloy, new in package. I specialize in hard to find watch parts so I usually have whatever you might need and all watch parts are unconditionally guaranteed. Images do an adequate job of representing the item.
