When I bought this frame from another forum it came with a BB

The cups thread into a sleeve which is removable from the frame, and is fixed into the frame via locking nuts. The problem is the sleeve appears to be French threaded (from looking through Sheldons gospel on BB's and alike).

Is it possible to source a replacement sleeve with more user-friendly threading? Im trying to fit a more modern crank and would rather be able to replace the bottom bracket than muddle around with trying to replace the spindle...

Thanks for any help
