Harman/ILFORD offer 46mm HP5+ as part of their annual large format special program. It's available in 50ft rolls good for respooling 127. It's a bit expensive though.
The ordering window for 2014 is about to open for late fall delivery. Order now if you want some.
Maco or Rollei (?) has brought back some black and white 127 but I think it's iso 100 or thereabouts.
