Incredible luck!

Bueno... It's a treasure because it's gramophonic, and by the serendipity... But it's this:

The needlebar crook is bent out of shape, and must be carefully bent back into shape... I don't know if getting it hot will help, so I don't break it!
The soundbox is pot metal, and the neck is missing some pieces, but I've successfully repaired this in the past.
It still has the diaphragm screw and paper washer attached!

I notice that you have very nice hand-writing.

It's my wife's handwriting!

It is a remarkable find, Inigo. It may turn out to be your "lucky charm", like when you find a coin, that you don't want to separate with, who knows!
Good luck with restoring it, for sure you never won't part with this soundbox/tonearm.

After restoring it, I will see how it performs. I already have a pot metal no4, and it outperforms any of my other bronze units... Each mica diaphragm and soundbox is slightly different, so it's not rare that the performance of two of them has a slightly different sound.
