Shooter gauge for a 1954 Williams Spitfire....a rusted out eBay purchase nickel plated by Chris at pinballplating.com.
I tried a decal but it looked terrible on the shiny surface.
Drano had good results with dry rub down transfers. I scanned and traced the decal in Inkscape and modified based on my original shooter. I chose Pantone 186C and had https://www.allout-graphics.com create the transfer for me. Had six printed think it looks great! Rub like hell until the colour on the transfer goes opaque.
