MGB and mounting very similar in basic principle, but the devil is in the detail and inside there are major differences in materials etc. Although the L and L1 are identical I think? The AS332L and L1 had a head with conventional bearings, the L2 and 225 have no conventional bearings in the head, just elastomeric thingies (multilayered blobs of rubber and metal discs). More blades on the 225.
