1. All listed companies have registeries which you may examine. 

2. If the parcels of share are so small as to be unmarketable it will
cost you at least $2.50 per offer.  Eg Printing and postage Usless you
are buying high price stock such as Comm Bank @ $30 a share it may not
be worth it.

3. After David Tweed and the National Exchange the law has been
