Several years old. Contact the number directly.
Lancaster Telephone Company issued these blocks several years ago. Customers swap carriers every few years, so Lancaster Telephone Company probably no longer holds them. Try calling any number you're interested in. If a person answers, you've found the current owner and can negotiate with them.
A long shot: if you'd like a watch in case we ever gain access to Lancaster Telephone Company's inventory directly, you can register your interest. We don't currently have visibility into number changes within carriers, so don't count on it.
