Newby question: Best way to enhance very poor details in .tif file

[Cheshire]

The .tif image here dates to 1905; it is the original and is not at all clear. I have played around with a copy of it for a while but I really need some expert help. I have uploaded the .tif, a crop from a larger .tif saved with no compression, to preserve as much detail as possible, which is unfortunately not a lot. 

It is a registered design of watch movement and should show the outlines of the bridges and cocks, somewhat like the photograph also attached although that is a hunter layout whereas the .tif is of essentially the same calibre in an open-face layout. Ideally, I would like the white lines around the bridges and cocks to be clearer to show the resemblance between the two clibres. 

I am using Affinity Photo 2 on Windows 11.

Thanks for any help!

Not sure if this is a solution for you but there is so little information in the original image I would try using the Pen tool and/or Curve shapes available in APhoto to highlight the similarities in layout between the two mechanisms.
I obviously don’t know much about the subject, but more detail could be added in this way the more you do know of course.

Hi Mark, many thanks, "so little information in the original image", I thought that might be the case but it's always helpful to have someone who knows what they are doing confirm it. Your suggested solution looks great, thank you very much. 

 

Kind regards, David
