Bret Hart Bowling Ball

I bought this bowling ball off an old man in North Carolina cleaning out his storage buildings. I literally can find almost nothing about this ball except for the fact that it was a promotional thing back in the late 90s when you signed up for a specific bowling league you got a hat a shirt and one of these WCW/NWO bowling balls. There were a few different ones, Goldberg, Hogan, DDP, STING, Kevin Nash,Bret Hart and a  couple more. This ball is undrilled and has never been used. It needs a good polishing and I believe most of the grime and scuffs would come off, I got some off myself already with a little dawn dish soap and a sponge. The ball has a few Knicks and chips in it as well but no cracks. Let's be real though you're not going to use this ball. You're going to put it on display next to your smoking skull championship belt and a sting action figure. How do I know because that's exactly what I'm going to do if it doesn't sell lol. It's Bret the hitman Hart and what's cooler than that. Also I can't even find the weight of this ball, I tried weighing it and it gave me an error on two different scales. The only info I could find is they made them 12-16 pounds but I'm not sure which of the two I have. If you have any questions please let me know, I tried to picture all the flaws I could but this thing was incredibly hard to take pictures of.
