I'm not sure they would be worth much...but those old Hellbenders are great for trolling for stripers...and you can attach a Pet Spoon to them and catch the heck out of bass trolling them as they act like a down rigger and the pet spoon matches the small shad fry.
Those old Arbogast Mud Bugs...if wood, are really great and still work. One of the best stringers I ever saw from Toledo Bend back in the early 80s came from an old wooden Mud Bug.
My dad used to take me and my brothers fishing when we had a place on Whitney trolling those Hellbenders with a Abu spinner trailing it and caught a ton of fish this way.
I also used to fish tournaments in the 80's and saw a lot of guys fishing those Mud Bugs on Toledo Bend. I also learned to use them for night fishing on Fork by slowly reeling them in near the surface with that side to side wobble. We would take them and paint them black and then red on the bottom. I didn't catch a ton of fish but the few fish I did catch completely murdered that bait when they would hit.
