What type of print (nighttime nautical scene) is this - also - signature help

This doesn't seem to be an engraving or etching - I'm having a difficult time getting pictures to show the real texture of the ink and color of the paper because it is behind some very reflective glass. It's about 6" wide. It has what I think is a signature at the very bottom right corner but is very hard to make out. It seems to have been framed/matted various times before as there are yellowed squares of various sizes and shades on the paper(where different size blocks of the paper have been exposed to sunlight). Under my loupe I see no dots whatsoever - the second picture is of the supposed signature and gives some closer detail of the ink but again not great pics with it being behind glass. Any ideas of the age/origin/type of print/artist? Thanks much, again!

After reading up and looking at this w loupe I'm leaning towards aquatint. Just a guess though.

 

Yes, I think aquatint.

 

Got it out from behind the glass - here's some better pics:
