Monark silver king aluminum tricycle and can find no information or value about tricycles only bicycles where you look Thanks Pam?

Monark Silver King bicycles have a rich history and are highly sought after by collectors. However, I can not find any information about Monark Silver King tricycles. This may be because they were not produced in large numbers or were not as popular as the bicycles. Monark did produce a tricycle called the Monark Trail-Mate in the 1960s, but it is not known if this is the same model you are referring to.
