See images for further details.  These came in a couple of different strengths, and those that I can supply are shown in the drop-down list.  Mainsprings have been on the shelf for probably close to 80 years but I inspect all these super old steel mainsprings carefully before I list them, and I guarantee them unconditionally.  Not a common mainspring so get them while you can.  Images do a pretty good job of representing the item.\u003c\/p\u003e","brand":"Waltham","offers":[{"title":".015","offer_id":47451768127796,"sku":"PMA-WAL2221S-15","price":5.0,"currency_code":"USD","in_stock":true},{"title":".014","offer_id":47451768160564,"sku":"PMA-WAL2221S-14","price":5.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0849\/3341\/1124\/products\/488555455.jpg?v=1705271002","url":"https:\/\/www.vintagetimeparts.com\/products\/waltham-factory-mainspring-for-00s-2-0s-factory-no-2221-steel","provider":"Vintage Time Parts","version":"1.0","type":"link"}
