Determining the Age of a Marshalltown Brick Trowel

The earliest Marshalltown advertisement found is for a plasterer's trowel in 1899:

Marshalltown Evening Times Republican, 13 Oct 1899
Marshalltown introduced their brick trowel in 1908, as this press release in The Iron Age announced:

Their advertisements for Marshalltown's brick trowels show "THE MARSHALLTOWN" stamped in a curve on the blade. This design appeared in ads from 1908 to 1910.

Hardware Dealers Magazine, Vol. 33, 1910

In 1911, the design changed to what appears to be an etching with larger letters, "MARSHALLTOWN" in a straight line. The company used this at least through 1921. After 1921, US copyright law makes finding advertisements much more difficult.

Marshalltown's Catalog No. 27 from 1927 shows an etching with large "M" and 2 rings on wood handles. This etching also appears in Catalog No. 45 (date unknown). Trowels from this time also include the product number below U.S.A., but this information is not on the catalog images.

The etching above was replaced with a "MARSHALLTOWN" stamp, also with 2 rings on wood handles. Another version includes "USA":

It appears that product number was added next, and earlier ones have 2 rings on wood handles:

By 1974, pictures show the same stamp, and with plain wood handles:

USA

Catalog pictures are not always a good indicator of when tools changed. Manufacturers, wholesalers, and retailers sometimes used old printer's blocks or plates to save the cost of preparing new ones.
