What actors and actresses appeared in The Leather Pushers - 1930?

There seems to be a misunderstanding. There is no movie titled "The Leather Pushers" from 1930. There is a film called "The Leather Pushers" released in 1928 starring:

* Buck Jones as Buck Jones

* Olive Borden as Virginia Lee

* Yakima Canutt as "Big" Jim Brady

* William Desmond as "Black Jack" Randall

Perhaps you were thinking of a different movie or a different year.
