Sheaffer’s had a plant here in Australia. The factory was located in a Melbourne suburb of Heidelberg during the fifties and perhaps up to the early seventies. That was all I knew about the pen when I acquired a specimen produced by the late Aussie operation, and restored the pen back to its original working condition.
I was about to wrap it for Christmas present to my brother, before the US counterpart (fully restored, same colour and model) came up on the market at an attractive price point. Bang! I quickly snagged it. The second pen’s condition was much better, but between the two I had decided to keep the Australian pen simply because I went bugger all restoring it. So soon enough, the latter was cleaned, tested, and then gift wrapped. But before being mailed, I took pictures of the “Two Towers” for your perusals:
Note the different cap imprints: Sheaffer Aust. Pty Ltd vs Sheaffer’s Made in USA
Again, different nib imprints: 14K Australia vs Made in USA and US Pat. No. etc.
Snorkel tubes extended.
Enjoy.
