NOTES: This is the parallel version of the Norris No. 50M. Introduced as the Norris No. 51M in the 1914 catalogue, it is probably more commonly found marked with just 51 on the levercap. Often stamped on the toe is is the casting registration "REGD NO. 637729". The length of the plane was 7½".

Like other planes in the '50 series', the cutting iron rests on two metal 'bosses', thus providing great stability. A secondary function of these metal bosses was to secure the closed rear handle, which was sandwiched between them and riveted, screwed or bolted in place. The handle also held the adjuster mechanism.

Examples may have "MALLEABLE", "ANNEALED", "UNBREAKABLE" or "PATENT METAL" stamped on the toe or heel, depending on the era in which the particular plane was manufactured. Levercaps were steel or gunmetal and came with a number of different Norris marks or stamps.

The wood used for the handles and buns were either walnut or mahogany, usually with a dark stain applied.
