Don,
Is the South African
105mm SA83 the homegrown improved version of the
105mm L7 UK73 as shown as being used by
UNIT 004 OLIFANT MK1? I have as you know put off work on these units for a couple of years now. However it's time to address the issues for all the OLIFANT units in the OOB. Things I see are in dates (production vs service), main guns and system development leading to the deletion of at least one unit. Working it.
I have in the meantime a better pic for your consideration for the OLIFANT MK1A as shown in Angola in early 1988.

Off the grid until the next PP.
Regards,
Pat
