Original 1930 Parker Catalog?

[Jim Kremmel]

Good morning,
Any way to tell whether a Parker catalog is original? Based on the price list, I think this is a 1930 catalog. It has the word “duplicate” written in either pencil or pen on the first page. Staples look old, along with some staining particularly on the back cover. I’d consider it in fair condition. I’m probably going to part with this, and don’t want to unfairly represent it. Appreciate any thoughts.
