S'posed to be 120. See:

On my "new" Hetchins, I put on an old TA crankset, with 50-28 rings,
using a Shimano UN-71 bb, 115 length. This seems perfect for this
double, but the intent is to have the 50 tooth ring centered with
regard to the 9-speed cassette (12-28) and to use the 28 chainring
only as a "bail-out" granny. http://sheldonbrown.com/

No, the simplest solution is to get a TA bottom bracket. See above.
