Except for updated versions of the 1937 whistling billboard and trackage, all of the products offered in the 1941 catalog had been designed under Gilbert's ownership. The 'Chicago' products had been expunged. The scale accuracy was emphasized in the catalogs and packaging. Already experiencing materials shortages (due to Lend Lease), no new products were introduced in the 1942 catalog, which was only slight different than the previous edition. Prices were printed on an accompanying unstapled sheet but not on the bound pages. Even the set numbers (i.e. 4117) were not changed. The cover of the '42 edition is distinguished from the '41 by a caveat about erratic availability printed in small red fonts.
