FoxRidge Outfitters used to sell the off set mount for the Hawkins and Renegade. You remove the rear sight and the small screw at the back of the barrel near the tang. The base mounts to that. Some advise, put quick release mounts on the scope. It will help when it comes to cleaning the rifle. You pull the scope and can still give it a water bath and scrub the bases easier...
I have some plates but am not sure how they would work for you. Checking them, they are a plate the attaches to a White Mountain Carbine, Pennsylvania Hunter orRenegade. Ibelieve thisplate then allows you to put a base of somesort on the different mounting screw holes on them. I found a place that had a bunch of them and bought them out.
That one listed on the auction looks like a off set base. But is is made by Weaver so I could not swear to that.
