Can anyone help me with this:
I recently found a 20mm shell case in a cellar, and I thought I could ID it after a few easy seaches on the internet. I was wrong!
The case is “about” 20mm in diameter (the top is a bit buckled) and 11 cm high and therefore most likely for a Hispano 20mm (got that from the internet).
But the headstamp is the real mystery. It bears the marking XF 5429 and very faintly at the other side it says KE 5179.
It has left me (and quite a few people at warrelics.eu) bewildered, so if anyone can shed some light over this mystery, it will be most welcome.
