Members

Purchase an ACMOC Membership

When you purchase an ACMOC membership, don’t forget to choose a chapter to be a part of. We recommend selecting the chapter that’s closest to where you live. That way you can take full advantage of being in a chapter which includes meeting other ACMOC members, sharing information, and the chance to see a lot of antique Cat equipment at chapter meetings and member events.

As a member, you are entitled to receive the club magazine and have full voting rights in club elections. Memberships are annual and are good for one year from the date of purchase. ACMOC does not sell its membership lists to third party vendors but may make your information available to other members upon approval.
