Back in the day, I don’t think Centuri ever listed the ST-9 tube in their catalog. Besides their Mini Max and Enerjet line (which is outside what we are talking about here anyway), they did not offer a D engine (and hence motor mounts of that size) until their 1980 catalog, with their ‘Magnum D’ line. And even then, just plain old tube stock of the 24mm size was not in their catalog. So, that size tube, as an “ST-9” never was really in their catalog. They did offer a line of Magnum D motor mounts to fit a 24mm D motor into their ST-13, 16, and 20 size tubes. However, by their 1982 catalog, they had dropped all their “ST” tubes and parts and had gone all Estes tubes, cones, etc., since they, by that time, were listed as a Penrose post office box and the end was close at hand. In their last catalog, in 1983, they did not even list tubes, cones, reducers, etc. at all, sadly. I think the first time I ever saw a tube labeled as an “ST-9” was in Semroc’s tubes offerings. So...that may explain why the list you referenced for David did not show at ST-9. Earl

I thought that might be the case. I was a little surprised at seeing Bill include it in his responses to David.

Speaking of which, there are two signs of advancing age. One of them is memory loss. I forget what the other one is.

Jay - yeah, eRockets is where I got that "same as BT-50 ID but .024 walls" bit. 0.950 is the same ID as BT-50, but they only have .013 walls....
So....what were those signs again...?
