This tubing would be great for the Smoke section on this rocket but would be absolutely perfect for a project near and dear to my heart: 1/10 Black Brant V.

A 1/10 Black Brant would have a 22.5 inch section of the new Series 17 with a section of Series 16/BT-60 at the bottom for the unusual reduced diameter section at the bottom of this Black Brant. Some fins, a 5.25" Series 17 bezier nose cone and Series 16/BT-60 engine mount hardware and you've got it; a rocket in present day use with ties to Canada and the United States. From here, you could do Black Brants VIII, IX, X and XII with various American boosters, with XII being a Talos-Honest John (M50)-Black Brant V with a Canadian Nihka fourth stage.

There are probably other rockets to use this tube for scale purposes but other than an Australian Jaribu, I can't think of any.

So if Semroc/eRockets or Apogee or Estes (call it BT-64 or something) wants to expand the product line, (or develop a new, non-military, scale kit) well, here you go.

This is weird yet wonderful--just this morning, I was brooding over the relative lack of sounding rocket scale kits, and of "mix-and-match" parts that would enable modelers to depict different rounds of various types of sounding rockets! I hope John Boren reads this thread and takes the suggestions of the posters here to heart! (1/10th Scale kits or scratch-built models of the various versions of the British Skylark sounding rocket--whose Raven, Gosling, and Cuckoo motors were the same diameter as the Black Brant I, II, IV [first stage], V, and Nihka rocket motors--could also be made using Series 17 tubing.) Also, regarding Black Brant models of Deci-Scale size:

In its early days (the 1970s), Semroc also made a 1/10th Scale Black Brant III (see: http://www.ninfinger.org/rockets/ca...70semroc14.html ), and Taras Tataryn's 1/10th Scale ARG (Advanced Rocketry Group) Black Brant III kit (which Sunward and then erockets took over, see: http://www.erockets.biz/advanced-ro...el-rocket-kits/ ) is/was the same size. With a first stage made of the Series 17 tubing, the 1/10th Scale Black Brant III would become (with a conical stabilizer/transition in place of its single-stage version's fins) the second stage of a 1/10th Scale Black Brant IV model. (Taras also had--and may still have--a full-scale [inert, of course] Black Brant IV version [called the Black Brant IVA or IVB; I forget which], which had three small delta fins on the second stage's conical stabilizer, for additional stability.)
