For 1961, Ford dropped the full size Sedan Delivery and replaced it with the compact 1961 Ford Falcon Sedan Delivery. It was not called a Courier. It appears that the 1961 Ford Falcon Sedan Delivery didn't arrive until later in the model year, as it is not included in the original Sales Brochure that only shows the 1961 Ford Falcon Ranchero. Hope that this information helps.
