These wheels will fit a Class 08/.57xx/94xx Chinese production also retro fit on Poole production. Providing the centre wheel is of Chinese production.

Note you will have to transfer the con-rods and pin from the centre wheel over from old style locos ref Nos CL08/GP tank/94xx/57xx to the new wheel. Important do not attempt to mix the new wheels with the old wheel type on the same chassis this won't work.
