The Gadsden Purchase Scam
Mike Johnson of the Time Patrol travels to 1852 New Mexico Territory to keep a crook from 2217 from screwing up the Gadsden Purchase. He takes weapons and other items from the future to help him in his quest. This was written at the request of several readers to combine a Western with a Time Travel story. I hope this meets with your approval. There is no overt sex, though the characters do talk about it.
