The No. 15 premium jack bench plane was produced for over thirty-two years across five different types.

Type 1 (1929 to 1935)

There were one changes what can be found while the type 1 planes were in production. The patent number was stamped on the face of the lever cap at the end of the production run. The patent was approved on September 8, 1931. Sometime shortly after that date, the press was setup and ready for work.

Type 2 (1936 to 1941)

The changes to the type 2 planes allowed Millers Falls to consolidate their production so that the same body and frog castings could be used on the premium line and the Craftsman rebrand line.

Type 3 (1942 to 1948)

The start of World War 2 limited the use of brass and the import of cocobolo. As a result of the shortages, the company switched to a single steel bolt to secure the stained hardwood knob and tote. The recessed depth adjusting nut was switched from brass to nickel or a blued surface.  On the cap, the background around Millers Falls was not painted for at least the first half of the period. The frog remained red and the stamp on the iron will have the Since 1868 trademark.

The company also limited the production of the corrugated type 3 version to the public. At the start of the type 2 second release, the corrugated version was back in full production.

Type 2/2 (1949 to 1952)

Millers Falls returned to using brass and cocobolo wood at the end of the forties. The knob and tote will be secured with brass waist nuts and have a recessed brass depth adjusting nut. To distinguish this type from the previous type 2, the trademark on the iron will be stamped “SOLID TOOL STEEL” .

Type 4 (1953 to 1965)

It is easy to identify a type 4 plane with black frog, full brass depth adjusting nut and the tigerwood used on the knob/tote.
