To keep factory lines running without violating resource restrictions, Singer chemically blued or phosphated their steel parts. Blackside components are rare and increasingly sought after by collectors and restorers.\u003c\/p\u003e\u003ch2\u003eCompatibility\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eSlide plates (#54512 \u0026amp; #54513):\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eSinger 28, 128\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eNeedle throat plate (#8240):\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eSinger 27, 28, 127, 128\u003c\/li\u003e\u003c\/ul\u003e","brand":"CMSS","offers":[{"title":"Default Title","offer_id":31221988425826,"sku":"VO1849","price":48.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0767\/4681\/files\/IMG_3046.jpg?v=1779282550","url":"https:\/\/www.vintagesingerparts.com\/en-ca\/products\/original-singer-blackside-bed-slide-plates-needle-plate-parts-54512-54513-8240-singer-28-128-wwii-era","provider":"Central Michigan Sewing Supplies","version":"1.0","type":"link"}
