Perhaps this is the eccentric locking version for use with stripped threads? If so, turn each side to the loose position and pull it out. Also, you may face stripped threads so perhaps leave the BB and use a Stronglight 49 for the crank if "good enough" will do.

I assume it was made in the late 1970¹s and has a 26mm nut on each side and no lock rings. Turning the nuts in either direction makes no difference to the positioning of the BB shell or axle as far as I can tell. It looks nothing like the later Edco BB on the CR site I have close up pictures if anyone is unsure of what I am describing. Sheldon Brown site has no mention of this model BB Any suggestions gratefully accepted. It is in a 1951 Bianchi Paris Roubaix that I am hoping to restore and it needs to be removed!!
