That's the closest match, being the same ID but slightly larger OD (0.002"). The 62 catalog says these were "ivory-colored tubes", and I think another discussion said they might have been hand-wound and parallel-wrapped.
Additional information to overload your brain cells... 
The BT-2 tube had the same diameters as BT-1, but had a different length (shorter, I think). The 62 catalog suggests this to be the case, as it offered PNC-1 and PNC-2 nose cones together with the BT-1 tube. The BNC-1A nose cone fit the BT-1 tube. However, the BNC-1 nose cone fit the BT-3 tube. Clear as Mississippi mud, right?
BT-3 was the original tube for the Scout...
The closest nose cone to the original BNC-2A looks to be the SEMROC BNC-30C (spherical). I think the length of 1 1/8" listed in the 62 catalog included the shoulder length. |
