Captain Wonder Strength Gauntlet
Where would you place this Golden Age character strength wise :
Using google and wikipedia for "guesstimates" on the objects he was lifting, I got the following :
1) WII Era German tank : 20-30 tons
2) WII Era US Bomber (looks EXACTLY like the Super Fortress Model) : 60+ish tons
3) Modern Space Shuttle : 80+ish tons
No numbers on the huge @$$ barge he was towing or the weight of the rocks he lifted to free those kids from the cave in. He didn't appear to be straining during any of these feats either.
IMHO he's at least CL75 (maybe even CL90). Looks to be stronger than She-Hulk, Colossus, Luke Cage, Rhino; but weaker than Thing or Wonderman who are low CL100s.
Keep in mind this isn't a fight (he's actually horrendous H2H). This is simply a contest of strength.
