Black n decker 8’portable saw question

[Brandy 3160]

Hey y’all! Been cleaning out the new house we just bought came across a 8 inch portable saw. I know it was made before 1976, but cannot find any other information. I am enclosing a few pictures. If anyone has any ideas or advice on how I Can find the information or if any of these old tools are worth anything. Please let me know. Thank you.
