Teague chokes are the only make of choke tubes that would not detract from the value of that gun. Infact, if there were two identical, contemporary Purdeys (not talking vintage guns here), and one had Teague chokes and the other didn't, I would pick the one with choke tubes without hesitation.

I have a sxs that Westley Richards installed a set of Teague Invisible choke tubes in, and they are marvels in both appearance and function.
