Re: HRO and BC348
The HRO's I owned were very well made, they were well thought out and designed (Millen, Hoover etc) I don't think they were built in a "rush" they would have left the factory with the alignment spot on, the rotor sections on the tuning gang should all be in line, the outer rotor plate being tweeked for fine adjustment, over the years many have been got at and fitted with go faster modifications etc.
