Listed in Horst Auction website as: Unusual “The Victor” Patent, brass-framed adjustable blind nailing plane with adjustable pitch & extendable arms. Stamped: THE VICTOR, JOHNSON’S PATENT.
Not entirely sure how this plane is used. The previous one listed on the web reads as above. This one has most of its original plating + a blade and blade holder and seems to be complete. Going for sale on the online store.
