We had a similar one at my Parents dairyfarm in the 70's, 'twas painted yellow.

that has legs of unequal Angleiron and different bracing to your examples and also has a drumrack between the legs for decanting said drums.
Just remember these thing were not set level, but supposed to be slightly sloping downwards with the outlet at the higher end to trap any water in the bottom....well at least that was here in NZ, you guys might not ever have had thought about that.
