I am restoring an Oliver model 312 corn planter.  I need someone with a manual for a White model 5100 corn planter to check the manuel to see how many inches apart to drop corn seed for a planted population of 27,5000 in 30 inch rows.

I can then, by trial and errror, set my model 312 to drop corn seeds the same distance for 30 inch rows on the 312.  The book for the 312 only goes down to 36 inch rows for corn.

Thanks in advance
