Help with Salt and Pepper shakers

[daddymacka]

HI.

Just wondering if anyone would have any info on these old wooden salt n pepper shakers with napkin rings. The salt shaker and one ring has "TSS Zealandia" on it and the shakers stand approx  8.5cm high with their corks still inserted.

I do know that there was a TSS Zealandia operating in WWII. so whether these tie into that or were made as a touristy thing after ????  I only know that they were around in the early 60's

Thanks for any info given

I've seen other items such as rulers made by what looks like the same maker, with a sticker 'Native Timbers Of New Zealand '
