RMU Belvedere is a revival of Heinrich Wieyncks design, which was released by Bauer in 1906. The font was completely redrawn and redesigned, and comes with a long s, two framing elements and two tailpieces.
Get the long s by typing [alt] + b or turn the round s into a long s by using the OT feature Historical Alternative. Start making the frame by typing [alt] + >, and continue with [alt] + <. The tailpieces can be reached by typing [alt] + [shift] + p or [alt] + p respectively.
