The recently discontinued version of Klean Strip Aircraft stripper was the best. It could clean off a modern engine in just a few minutes. They have since reformulated it but I suspect it would still be very effective at removing that paint.
As for paint, most all my repaints these days is with PJ1 Special Satin. Pretty close match in sheen with both Post War and modern MTH and Lionel steam and durable too.
This is a repaint.
