These were made by Proline. In about 1992 or 1993 they redesigned the Point Blank, it was then the Point Blank New Wave CR41. 41" ATA. It had a built in overdraw. Smooth draw. At the time they were excellent bows. And actually, I think they still are good bows.
Does your bow have a 'built in' overdraw, and is it reddish/brown cammo in color? If so then it's the New Wave, if not it's the older Point Blanks. Later Proline made the Tsunami based on the New Wave designed but I think without the Point Blank name.
One idea you may want to do is search for it on Ebay. Anytime I want to get an idea about a piece of equipment I'll do a search on ebay and get info by pictures, and stated specs on people who are selling. Search for Proline Point Blank
