Courtley was a sub-brand or second of Custom-Bilt and quite inexpensive, retailing for $1.79 in 1957. However, His Nibs was another Custom-Bilt sub-brand or second that was even cheaper, retailing for $1.00 the same year.
Below is an ad from Rogers Imports Catalog of 1957, showing different Courtley shapes for sale, describing Courtley as an economical version of the distinctive Custombilt Pipe (as spelled in the ad). They had a walnut finish and vulcanite bit. And they were packed one dozen to a display box.
