This is an old but very good Catechism by Rev. A. Urban,
they were published in 1902, 03, and 04,
you can read them free online, since they do not have a copyright, but i might also work to get them posted here on the forum like i do with the other books, since i don't know how long they may stay up on that site.

well, here they are -

Teachers Handbook to the Catechism Vol. 1

Teachers Handbook to the Catechism Vol. 2

Teachers Handbook to the Catechism Vol. 3


these are my absolute favorite catechisms, and i'm sure if you give them a chance, they will be yours to,

currently most Catholics seem confused and mislead in the true teachings of the church, so i think it's just so important to read things like this and educate yourself in what the church taught back when there wasn't this massive confusion,
people knew the teachings of the church back then because of books like this! so start reading!
