National Model Railroad Association 3 ring binder of NMRA (RP) Recommended Practices and Standards. Updated to 1991 releases. Good condition, from a dry smoke free home. The National Model Railroad Association (NMRA) was founded on September 1, 1935. It was established by a group of about 50 modelers during the first national convention in Milwaukee, Wisconsin, with the goal of creating uniform standards for the model railroading hobby. I am finding new homes for many of my softcover model railroad books. Winning bidder pays $8.22 Media Mail USPS  shipping in CONUS on this book. Payment is due within 5 days (including weekends) of auction close. I am not a business, so all sales are final. If you have a problem with a purchase, contact me. We can work it out.
