G'day prd
I'm glad that you raised this timely issue!
I'm sorry for this long reply - but we need help.
The link is not there yet because the article has 'issues' that I have
not resolved. I think this will take some time.
The brilliant
Gadge has given me fantastic info that suggests the article
needs to be revised, if necessary. I feel it is necessary

Yes, a Google search does reveal as you describe.
Mate,
you may be able to help. These are some points:-
[1] It would appear that Owen Cox designs and trademarks were
privately sold at some point late last century.
Cox Industries has no direct relationship with the
Owen Cox family.
Owen Cox died in 1977. The following article is informative, but I feel
there is error of historical importance:-
http://www.couriermail.com.au/busin...s-story/dbd6657d4085ac0d7e1e5f73db7355f2My quest is to find
who made Australia's first ride-on.
I have argued that Cox was not making ride-ons in the 1950s,
but made their first ride-on, the
Mowmobile in the early 1960s.
[2] The photos are not a model record - but they need to
give accurate historical information as to what Cox was doing
in 1960 - given the signage. I need to clarify exactly what
the
Grass Master and
Mow Master were!
By advertising Garden Master, Grass Master and Mow Master, the
easy conclusion is that there is some maker commonality. I have
said that I do not believe that is the case. That is un-resolved.
[3] The Google search reveals that Yellow pages and True Local
have records that suggest an Owen Cox & Co did survive at the old
address. The thing is that the True Local listing shows a linked
website. Here is a screen capture where I have inserted the linked
address (Kawasaki!!!):
So, I'm guessing that the retail store survived and remained in the family,
but had no connection to the new owners of the manufacturing arm.
So any help in this area to improve the record would be appreciated.
Gadge has located the patent for the "live Drive" transmission,
but I will only include that when I am confident in writing a
history record of a Cox model. I am no Cox expert.
p.s. the Google Maps search revels the new building that replaced
the old building in the photo record. That building housed the
Owen Cox showroom (downstairs) with offices upstairs. The factory
was behind this with access from the side street.
The 2016 image seems to show that the building is vacant.
My best guess is that Owen Cox and Company is now defunct, at least
at this address, but more investigation is needed.
All very interesting.----------------------------
