There exists a long-standing disagreement between bubble chamber measurements of the single pion production channel nu(mu)p -> mu(-)p pi(+) from the Argonne and Brookhaven National Laboratories. We digitize and reanalyze data from both experiments to produce cross-section ratios for various interaction channels, for which the flux uncertainties cancel, and find good agreement between the experiments. By multiplying the cross-section ratio by the well-understood charged-current quasielastic cross section on free nucleons, we extract single-pion production cross sections which do not depend on the flux normalization predictions. The nu(mu)p -> mu(-)p pi(+) cross sections we extract show good agreement between the ANL and BNL data sets.
