Often the pattern and look is unique to Craftsman, but not always.
If is a common tool I think it is more likely to be a unique Craftsman look.
If it is a four way screwdriver, or precision tool, or something less common like that, my experience is that it will look like the manufacturers tool with a Craftsman brand on it.
I think you have a better than 50% chance it is a Craftsman. The only problem is that the pattern of the handle is different.
I checked Craftsman catalogs back to 1949 and they all have plastic. I assume it is an earlier tool.
