Different names same tool Continental, German, and shallow roughing gouge. Toolmakers make this tool in different sizes too. Think Packard Woodworks sells a ¾" HSS German spindle gouge made by Hamlet Tools for $61. Normal Hamlet ¾" U-shaped roughing gouge sells for $50.
Had a Sears's ¾" shallow roughing gouge (red handle) many years ago. I liked it for finishing cut on long spindles. Wore it out long before got around to turning pens.
Harbor freight red handle tool set has a couple shallow gouges not sure what size.
Did a Google search for ¾" shallow gouge came up with this. Did not see it in their catalog but could be there.

I like both normal and shallow roughing gouges. These days get by with Henry Taylor ¾" and 1 ½" normal U shaped roughing gouges. Do use the ¾" gouge for turning pens blanks. Either normal U or shallow style will get the job done.
Know would not pay more for continental, German, or shallow roughing gouge regardless of who made it!
