Re: [ATM] Inventor of Mangin mirror dies?

["Bevan Harris" <ngc2070@gmail.com>]

Thank you all.

It quite evident that the Mr Mangini, late of Perth, is not the
originator of the Mangin mirror.  I've shared this news with the lady
at work, and she is going to try to gather more information from one
of his sons.

I won't say "watch this space", but if I find out something
worthwhile, I'll let you know.  It will be interesting to find out
where/how the confusion has arisen.

Cheers
Bevan
