Brian shared this video. I don’t have away to embed it here, so you’ll have to view it on FB. The narrator notes that the jeep has been sitting since 1994, but it only required a little oil to make them work again. The narrator concludes that because of this the design was a good one.
My only caveat on that compliment is that near the end there’s a closeup that shows how bent one of the arms is. For better or worse, the bending of the levers has been one of the weak spots of these of this design.
