There are a fair number of 20th century USMC mameluke swords out there and the current major importer Marlow White sells the WKC goods.

Others making the official pattern are Windlass from India and I believe it is MArto that brokers the official U.S. military swords made in Spain.
It has been awhile since I looked at this site but they used to make the U.S. patterns

The Ames sword Company can and sell this pattern as well but they source the blades themselves from Windlass or another India factory.

Keep in mind that the Cold Steel offerings are not official or approved U.S. military patterns and will not meet guidelines for uniform use.

There are a good many post WWII USMC mameluke swords out there. All will be somewhat similar to the one we see above. Pre WWII swords with a solid provenance and officer's records will reach a premium but unless we are looking at one of the very early 19th century mamelukes, or premium swords late in the 19th century, they are not terribly expensive in the grand scheme of things. The Msrine' nco sabers that were a crry over of the American Civil War era officer's swords that had supplanted the mameluke for officers during the 1850s and the mameluke re-instated later in the century.

There used to be several German makers such as Horster and Eickhorn. There were American retailers such as Zubco that sourced worldwide, including Japan and iirc Thailand.
While the initial 1827 contract of the USMC mamelukes was indeed from England, few were being made in England for the American market after the turn of the 20th century.
There is one of many neat articles on the early swords here.
