A military marked silver badge from Portugal

[luciano]

Hello,
I am writing you about the brooch you can see in https://photos.app.goo.gl/tjATHTkDYo2dcve88
It should be a badge of the Order of Christ, established in Portugal, which I have bought as a gilded silver filigree: as you may see, it presents two pairs of marks (in two distinct parts).
I have thought it could have been made by a Portuguese workmanship but I do not find a match with the Portuguese marks and so I hope in your kind help.
Thanks a lot and kind regards,
Luciano

To me it looks a lot like Masonic type , Templar theme , unfortunately I can’t help with the marks
