Braze on?  I seem to recall that your Ridley Helium frame was made
from carbon fiber?  How does one braze to carbon fiber?  Perhaps you
meant front derailleur hanger or mount" like these?
<https://www.google.com/search?q=front+derailleur+hanger&tbm=isch>

This is probably what you bought on eBay:
<https://www.ebay.com/itm/255674322671>
Complete with a photo of the front derailleur hanger:

<https://i.ebayimg.com/images/g/8PUAAOSwSIdkC68u/s-l1600.jpg>
The rivets look like aluminum (steel would be plating or shiny) with
some kind of insulating gasket between the hanger and the CF seat
tube.

Looks like genuine hangers are available:

You can also buy genuine Ridley rivets:

If those are the parts, then I don`t see how it is possible to install
the hanger "slightly crooked":

"It turns out that the front derailleur bracket was installed slightly
crooked."

I`m suspicious.  Why haven`t you posted any photos of your Ridley
project bicycle or of the areas where you were having problems?  Why
were you ready to give up on the Ridley, immediately buy a very used
steel Serotta frame and are now back to working on the Ridley?  Seems
a bit strange.
