Big Block smog tubes, anyone recognize these?

[AnthonyS]

Hi Gang,

Anyone know what these are? I'm going assume OTC replacements, because of the funky, removable, screw in ends on the two ports on one side...

Anyone recognize these?

They are brown and appear unused.

Application guesses?

Thanks in advance,
Anthony
