The Hanus 28ga Birdgun I bought a few years ago (Ugartechea) was marked skeet/skeet . . . but the Spanish markings were cyl/IC. The chokes measured .000/.004, so the Spanish markings were the accurate ones.

Terc, I also recall that Bill liked small shot and open chokes. He sent me some Lyalvale 9's and some Activ 7 1/2's to try out. I didn't think much of the Lyalvales. The Activs were 16ga, an ounce of nickel plated shot pushed by something like 3 (or maybe even 3 1/4) DE of powder. I don't recall the velocity, but they were very "snappy" to say the least. I figured the high velocity might result in blown patterns. Not in that case. Those shells threw great patterns, although I hesitated to shoot many of them at paper, because all my 16's were pretty light. Used them very effectively in the open barrel of my 16's on mixed bag quail/pheasant hunts in Iowa (back when we had good numbers of both). There was a bit of "killing on both ends" involved, however.
