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

Very popular Philips NZ 7-transistor portable radio. 

There are two main versions, one with a local/distant switch and this (earlier) one with the gram input option for connecting a record player.

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.

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.
