Contempora trumpets and cornets with “Diatonic” compensating tuning mechanisms were available in the early 1950s, if not earlier. Unlike the standard Contempora models, which had a trigger mechanism connected to the first-valve slide, Diatonic models with the “Tune-As-You-Play” (TAYP) mechanism featured a trigger connected to the main tuning slide that allowed any note to be adjusted as the instrument was played. Trumpet in C models were added to the catalog in 1959.
The “Contempora Diatonic” trumpets were rebranded as “Renascence” models in 1959 and went out of production as early as 1961 when Reynolds was sold to RMC.

Notes and Quotes
1953, 1958, 1959 Roth-Reynolds (Renascence model):
A truly sensational trumpet with ‘tune-as-you-play’ mechanism. Its amazing tuning features, superb tonal qualities and unlimited flexibility have made the ‘Renascence’ trumpet in a comparatively short period of time the choice of the country’s most discriminating musicians.
