ATSF steam engine number boards and decals are available from www.atsfnscalemodels.com. See the website for more info under CURRENT PROJECTS (and then the latest topic) and under PICTURES. The number boards come in 5 different sizes to fit the handrails of existing steam locomotives (see pictures below and description on website). The decals are printed in STENCIL GOTHIC (as close to prototype as I could find) on an ALPS printer and should be treated just like Microscale decals (28 different engine numbers with 6 identical numbers each). Engine numbers 664, 1524, 1627, 1790, 2522, 2531, 3197, 3412, 3420, 3440, 3458, 3460, 3465, 3733, 3768, 3784, 3808, 3825, 3909, 3932, 4001, 4010, 4039, 4196, 4197, 5001, 5011 and 9446 to fit a variety of plastic and brass engines. Number boards are $1 a piece, 1 decal sheet will all numbers is $4. For ordering and mailing see the website. A Word document looking like the decal sheet is included to make identification of the different numbers very easy.
