Nice diversion for me.
My dad worked for Hardleys Ltd. (Plumbing merchants) who merged with Samuel Parker & Co Ltd to form "Parker Hardleys". He was a travelling salesman covering the wider Waikato from Hamilton. Copper pipe, Crox nuts & solder as well as tapware, porcelainware and waste fittings etc. Plumbers used 'hemp' in the days before teflon (PTFE) tape which was hailed as a wonder product when it was introduced.
As well as the aforementioned Roller Doors, Dustbins, Flashings etc. I recall there was a division at Sam. Parker & Co, Ltd. making pressed stainless steel kitchenware (Butter dishes, cheese covers etc. some of which had hardwood handles) We have many 'sales samples' still in our late mum's house. Very retro now.
Hardleys made an 'Up & Over' garage door with galvanised cladding on a timber frame and heavy spring-assist. - two examples of which are still performing well at home after 50 years. A galvanised long-run roofing was developed with a unique profile that enabled you to click each new length into the previous one and needed few retaining clips. (Our still looks good (unpainted) on the same garage.
At the time of the companies' merger I was excited about the prospect of a 'sample' Parkercraft being added to dad's sales inventory - Sadly that never happened.
A disappointment for a budding teenaged fisherman.
Thanks for the memories though.
