Don't know much about it I got it with a bunch of model A parts. Looks to be a solid rocker box no cracks or damage to the body the chrome is decent for being a vintage part. The bolt tabs look to be all solid no cracks that I can find and the box isn't warped as far as I can tell. The Rockers are intact its not show room perfect but would be a solid replacement for an older restoration.  I believe it's a sportser iron head but I'm not an expert. I am going off of photos.  Ask all questions prior to bidding.
