Default Need Cross number body tube

I have a Centuri Spirit of America kit.
Had to open it to access things for another member.
Noticed that the body tube is wasted.
I must have the only kit in existence because I can't find a darn thing online about it.
Instructions shows part number 30352, 18" long.
Anyone have an idea what size it is?
I don't think Centuri used the same size tube as Estes, which I have a ton of tubes in all sizes.
Any help would be greatly appreciated.
Thanks

https://www.flickr.com/photos/94793351@N08/9741485636/ shows a CR #30164, which is a 20-50.

This looks to be a standard bt50 tube, although I can't vouch for the OD.

try inserting the nose cone into a bt-50, if you have a lot of overhang but otherwise it fits, then what you need is a piece of series 9 tube. this should be available from erockets, failing that a chunk of 'Loc 24mm motor tube' should work nicely.

It is BT-50, listed as .98" in the catalog, rounded up from .976". It came along at the very end of Centuri as a brand (81-83), which means it actually came from Penrose instead of Phoenix.

If you look at the Comanche kit and a few others, you will see that it's 18" BT-50 with the same part number.

Thanks guys, BT-50 I have over a dozen 18" sections.
Time to start a clone with balsa fins.
Unless someone knows where to get heavy card stock like the kit has.

Too much glue up for the worth.
I have sheets and sheets of balsa on hand.

Tagboard. Saw some of that in Micheals the other day in the drawing pads aisle.

Not sure where the closest store would be, I've never seen one.
Closest Hobby Lobby is 80 miles I know.
Could order online if it wasn't too much and I can twist the wife's arm hard enough.
I'll check into it.

Unless you are looking to get the die-cut fiber board finish of the old original fins that look good one one side and not so good on the other, in addition to the swelling at the edges back in the days when we didn't know how to deal with them., I'd go with balsa.
