Time wise it was a bit of an eye opener. The leather was about 6 ounce some thing from a scrap bag. I cut out from a standard pattern piece, but since it was so light, I bent it around the mold and did a trim with leather scissors. I also cut out a tab for the back to hang it, I think, or maybe there was a fold over piece. Once I had the shape, I marked several points and ran the decorative stitching more or less freehand on the machine, then sewed the belt loop, then sewed the side seam. The belt actually took longer because I had to mark, with a ruler and cut it out, then run the strap cutter. The piece was too short so I had to joint it neatly with a patch, and punch holes and slots.
The interesting part is this is about the effort that probably would have gone into s similar holster from the period, if it was just a utility pouch. Obviously the best work was pretty special. But it is instructive to just do a flat out piece and not laminate, or glue welts, or stain, or stamp, or make sure the holes were punched centered to the thou, etc...
