Porthole maker identification requested

[Navatech]

Hi, I'm hoping somebody will be able to identify the maker of this porthole... There's a label on one of them but it's smudged just enough for me not being able to read the pertinent parts...







I need to identify the maker because I need some spare parts...

Thanks in advance for any and all help!...
