The Philips L3Z73T was manufactured by Philips Electrical Industries of N.Z. Ltd in 1958.

Other radios based on the same chassis:

Very popular 7-transistor portable radio from Philips NZ. 

This was the first release of the Transistor Ace with a later version dropping the gram input and associated switch - a local/distant reception switch taking its place.

Available in several colours, tan being the most popular.

Cabinets (among other locations no doubt) were produced in Christchurch in a cabinetmakers shop in Ferry Rd - A lady who's father owned the shop recalled making the tan cabinets and covering them as an after-school job in the 60's.  Does anyone recall the shop name?

Several different dial designs have been noted.

The primary New Zealand electronics industry trade magazine, Radio and Electrical Review, featured this model on the cover of their October 1958 issue.

General Construction Notes for Philips Electrical Industries of N.Z. Ltd:

Model codes are explained on the Philips brand page.  Philips early-mid century were probably the Google of their time - they had branches in many countries and a global brand that everyone knew - and were apparently happy to let engineers come up with new ideas and implement them.  Construction is often overly complex but very well engineered - although repairs can also take a complex path.  They used time-in-motion studies to find the most cost effective way to asemble sets and sometimes this means repairs can be nightmarish (if you've ever worked on a V7A Theaterette this will be all too aparent).  U suffix model numbers are transformerless (hot chassis) sets and great care should be taken, or the sets avoided altogether.
