Thank you for your message. There is a slightly different way the YRA402 is made and it is made to replicate the Traditional Rottenburgh models. Please see the extract below.
"The Rottenburgh family of Brussels was the leading provider of wind instruments to the Belgian market, supplying the court and the city's cathedral. Jean-Hyacinth Rottenburgh (1672--1756) made recorders, flutes, oboes, bassoons, violins and cellos"
