I would guess at nine inches long it would have been a T-20 tube and a conic 620C nosecone. Not sure if you could find the original metric tubes, or if you want to go on a hunt, but the BT-30 is about 18.5mm in diameter and a BT-40 is about 22mm. As for the nosecone - you may have to hunt that one. Once you have decided upon an approximation of the tube size, then you can search for your cone. If you go with a slightly larger tube size then your options for a conic nose cone will increase. Of course, there are any number of very nice people that will custom turn a cone for you.
