See images for further details. Recently came across a box of original Howard Factory mainsprings, all of them in remarkable condition given their age and considering the thin paper they were wrapped in. Paper stains do not imply a rusty mainspring - I check them carefully. I specialize in hard to find watch parts and all watch parts are unconditionally guaranteed. Images do a pretty good job of representing the item.\u003c\/p\u003e","brand":"Howard","offers":[{"title":"Default Title","offer_id":47452596830516,"sku":"PMA-HOWA328S-05","price":8.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0849\/3341\/1124\/products\/3082601147.jpg?v=1705290993","url":"https:\/\/www.vintagetimeparts.com\/products\/howard-factory-mainspring-for-howard-16s-no-328-steel","provider":"Vintage Time Parts","version":"1.0","type":"link"}
