Hello, I have a Body Solid Hardcore Gym by Powerline Body Building Gear, it says on the front of the butterfly top piece. I'm unable to locate a Model number. This home gym is approx. 15 years old & uses old fashioned free weights. In my opinion they work better than any square stacking weight equiptment I've used at any home. Therefore I have kept and used this home gym for many years. I just moved & the manual has disappeared.Highly recommend this product to anyone. Thanks in advance, Mrs. Lewis
