You know, Schrade Walden fixed blades were not barn burners in sales in those early years. This 145 pattern in Stratawood I first find listed in 1953, though records further back are sparse on these. According to Albert Baer, Ernst Gerling in Germany was Schrades Wondawood (Stratawood, Propwood) supplier into the 1960's.
The #145 was the same pattern and handle material as the 140, but without handle grooves in the Stratawood, and with a plainer birdshead pommel. First seen in 1953, it had a 8 1/4" overall length, a 4" hollow ground stainless blade, and aluminum alloy guard and pommel. It listed in 1955 for $4.95, was listed in 1957 as the 145, 145L, and 145WE (Wonda-Edge serrated blade), but gone by 1959.
The #146 was the same pattern, but with grooved Stratawood handles (like the #140) and the birdshead pommel. First seen in 1953, it had an 8 1/4" overall length, hollow ground stainless steel 4" blade, aluminum alloy guard and birdshead pommel. It listed in 1955 for $4.95, appeared in 1957, but was gone by 1959.
