Can't believe it is a self tapper, no spiky point to get the screw in the hole and started.

Looks to me like machine cut, see the abrupt stop of the thread under the head when the die opened. Means it was made by a real manufacturer.

If it measures 1.7mm then actual size is probably 1.8mm.

I have the Machinery's Screw Thread Book for 1937, 8th edition, can't see it in there but what a lot of threads!

Why don't you try going down the vintage camera route? there's forums, Facebook pages etc, and many collectors and repairers have spares salvaged from unrepairable cameras. As a collector of vintage hifi I keep a box of salvaged screws as there are many different types and sizes - none like yours may I add - but nonetheless very useful to me for my vintage hifi hobby. Camera collectors and repairers will surely have spare screws.

Here's a few links. Try placing a wanted ad on all of them for starters:
