Arcane Cane Corkscrew

Whilst rounding up the latest pieces that are currently for sale on my website at corkscrew collection for sale @ vintagecorkscrews.com , I also picked up this cane corkscrew. It is similar to the John Bull corkscrew in Don’s book, but this one seems to have an interesting grimace and a scarab / beetle / bug resting atop his head. Given that I cannot find a maker’s mark, this one is somewhat of a mystery. Any thoughts would be appreciated!
