pinion gear for chandler and price 10x15 oldstyle

recently purchased ,from a well intentioned member, a pinion gear for an oldstyle 10x15 c&p letterpress. Unfortunately i failed to realize it was oldstyle and i own a newer model. If anyone is interested in this let me know. Also any knowledge of a newer style 17tooth 3 1/2diameter pinion would be appreciated.
the one i purchased which is now available to anyone has 19 teeth.
