Router Plane. Cast-iron baseplate with an oval 41 mm opening and rounded front edge (25 mm radius). Behind it sits a 35 mm iron socket forming a double iron stop at the front and back, fitted with a 40 mm long, 6 mm vertical screw. A bronze nut with a 4 mm thick, 19 mm diameter round stop adjusts the cutting depth.

A special oval iron yoke with clamping screw serves as the iron holder. A 30 mm extension piece with a vertical sleeve (10 mm bore and clamping screw) secures the 83 mm × 10 mm depth-bolt on the right.

Underneath is a chipbreaker made from a 15 / 30 / 35 / 25 mm angle-iron piece with a 10 mm sleeve and clamping screw, adjustable by sliding. Two wooden handles, Ø 2.4 / 4.2 cm and height 4.8 cm, are fixed with bronze screws.

The iron is 11 mm wide with a 92° cutting tip, bent at the shank. The shank is a 10 mm square with chamfered edges. The top of the iron is 4 mm rounded with a guide groove. One side of the plane carries a 1-inch scale divided into sixteenths.
