The features of this plane lead me to believe (or hope), that this is by G.Miller, a favourite English planemaker of mine. I’m fortunate enough to already own two of his planes and the build quality is superb, not to forget the beautifully flamboyant touches here and there.
None so fancy as this gunmetal shoulder plane with ebony inserts and a ‘whale-tail’ wedge. The most striking feature being the ‘rhino-horn’ central infill, which thankfully made it through the UK postal system unbroken.
I’ve yet to pop the wedge and clean and sharpen the blade. No makers marks on this one, but Miller was known not to stamp all his planes.
