In the Febuary 06 Model Railroader, the "Build the Stoney Creek" article mentions how the writer used a radius guage by Ribbon Rail to help make curves with flex track. I've been searching left and right on google and can't find anything about this company or product. The Materials List on page 61 didn't even list the product. Has anybody here seen them? I was trying to see if they make any n-scale products as well (article was an HO railroad). Thanks.
