You have the later version with the pegboard back. It's in the 1955, 1957 and 1959 Craftsman Hand Tools catalog. The basic cabinet was the same in 1955 and 1957 for the mechanics and carpentry models, only the pegboard accessories changed. In 1959 there was only one version, no separate mechanics and carpentry versions. The 1959 likely had the Crown logo instead of the oval Heritage logo.
In 1960 the doors got pegboard holes as well and more normal pegboard hooks instead of the specific toolholders.
In the 1964 catalog they are gone.
From what I can see you have a 1955-1957 era one and it appears to be the carpentry one from the few pegboard accessories I see.
