How much does a bare aluminum spar wing weigh? A wing without any additions or modifications, such as a wing tank?

Fat Cub has two late 1950s Univair aluminum spar wings. They appear to be using original Piper ribs. I have not weighed them, but they seem heavy. Has anyone weighed their bare metal aluminum spar wings?

Thanks!

Craig
