Mochizuki (?), ice wart hog screws from Japan

Page from the REI 1958 catalog. 
The ice screw with the welded eye is unmarked so I have yet to figure out who created it. Shown in the 1964 Fisher and sons catalog is a photo of the ice screw shown unwelded as being manufactured by Grivel. I was able to find a ice screw which exactly matches the photo in the Fisher and Sons catalog. When I received the ice screw I notice it is created by Simond. Now the mystery continues.... is the catalog incorrect? Are both ice screws created by Simond? Is the welded ice screw actually a Grivel?
